@Jan Is my answer wrong? I am pretty sure that TsCl contains S=O bonds... chemistry.stackexchange.com/questions/61981/…
 
Jan

A: Which d orbitals of sulphur take part in the pi bonds of SO3?

Martin - マーチンUnfortunately this is an issue that is, even though thoroughly disproved, still taught in many books and schools. As Philip already pointed out in the comments: There is little to no contribution of the $d$ orbitals to the bonding in $\ce{SO3}$, as modern quantum chemical calculations prove (co...

Q: Where does the label ‘Dq’ to denote the field split in coordination compounds come from?

JanAs established in a previous question, coordination compounds typically have a field split between the $\mathrm{t_{2g}}$ and the $\mathrm{e_g}$ d-orbitals.[1] This energy difference can be explained by the crystal field theory which assumes negative point-charges approaching a complex and destabi...

A: Why is the bond order in the SO₃ molecule 1.33 and not 2?

Martin - マーチンThe bonding situation in $\ce{SO3}$ is a tough nut to understand. In a historical context this molecule belongs to the species of hypervalent molecules, that disobey the octet rule. The concept of hypervalence is still very much debated. Recently there was a question raised by ron, seeking for mo...

5
A: Substitution at thionyl chloride sulfur

Martin - マーチンI previously stated in the comments: Both are just as wrong or as right as the Lewis structure of thionyl chloride. Indeed thionyl chloride is a nasty little molecule when it comes to the bonding situation. This makes it also incredibly difficult to utilise it in quantum chemical calculatio...

@Benzene So basically yes; sulphur obeys the octet rule and tosylate or tosyl chloride do not contain double bonds =)
 
@Jan thanks! That is good to know.
I find this a little bit bothering
Although, all the questions do deserve negative scores
 
1:10 AM
That's just how it is. There are usually more lousy questions than good questions.
If you feel up to the task, you can edit a lousy question and turn it into a good one :)
That is always the ideal scenario, but we have to recognise that not everybody has the time and wants to put in the effort to do so.
Which is why most of them get downvoted, closed if necessary, and nobody bats an eyelid.
 
Yeah. I would do something if I could, but two of them are physics problems, one is homework/computational, and the last one can be google searched in five seconds.
 
give me a helpful flag @ortho
 
@pentavalentcarbon I don't see any flags right now
 
Is it a low-quality flag on a question?
Those go to the review queue, not the moderator queue.
I think.
 
1:19 AM
off-topic HW
 
Ah, ok.
 
hooooooooo boy I found a good one
hrmmmm look of disapproval doesn't work on my computer
 
ಠ_ಠ
 
installed some font package, time to restart the browser I guess
 
Do you all know if chemical graph theory holds any merits? It sounds like an interesting concept (especially for representing compounds in computers), but I don't know if I should spend the time to look into it, as it has limited functionality (no stereo chem for example).
 
1:47 AM
Dunno anything about that.
 
Haven't read about it in a long time either
 
lol, I am a CS/Chem major, so it sounds really interesting
 
though a lot of the text representations (SMILES, InChI) work by graph traversal and might be interesting to you.
 
Sounds cool, I will look into it
 
That paper looks very nice, maybe I'll read it properly at some point. I do know the field is very small.
and they will look cryptic
echo "export PATH=$HOME/psi4conda/bin:\$PATH" >> ~/.bash_profile
oops wrong room...
 
1:55 AM
lol
 
Jan
@pentavalentcarbon I'm disinclined to acquiesce to your request.
 
I said wrong room...
an owner can delete them if they want
 
Jan
I was trying to be funny …
 
I know.
I'm bad at internet-ing at night
 
Jan
Oh it’s night where you are, too.
That moment when you look at someone’s tagline, notice they have 1 rep, check their profile and find out they’re temporarily suspended and you just think ‘oops’ o.o

UGH
must be some mod magic
for determining sock puppet accounts, etc.
though I don't understand why people would want to do that
 
Jan
I … kinda do? I’ve been tempted numerous times to create a sock over at German to downvote my -2 post so that I can get peer pressure. I mean, it’s shiny, sparkly badges and magic unicorn points; who doesn’t love them? xD
 
When I die, I'm not gonna say, "I wish I got more badges on my Stack Exchange sites".
5
maybe it's because my field isn't capable of farming rep cough
 
Jan
So many things I would think and/or say if I die … most of them not repeatable here ^^'
 
2:10 AM
agreed
 
Jan
Another random comment: There I was asking myself why no rep came in until I realised that it was because of the -50 I spent on a bounty. For some reason, the notifier does not take negative values into account (which is unnerving).
 
Zhe
@pentavalentcarbon You forgot sudo
 
if you are sudoing that command then you have a big problem
 
Jan
sudos should always be applied to rm commands, especially those with the -rf flags, especially if they attack short full paths.
 
2:34 AM
I would make the look of disapproval but I don't have the right font installed...
 
Jan
Right, after having answered a few SE questions, let’s go back to organising references into BibTeX format for my thesis …
 
Getting one's bibliography entered into the format of preference is horrid. Once it's there, though... oh, so amazing.
 
Jan
The main thing annoying me is that I started using Mendeley when my main PC was still running Windows … and now I’m basically jumping back and forth between Linux and Windows with the KVM switch just to use Mendeley to correlate papers with DOI entries and bibtex-entries … Oh boy =C
 
2:49 AM
<shudder>
yeah, interop is terrible.
 
Jan
3:20 AM
By the way @penta, I just saw your edit pop up in the queue, started to read and try to understand the text but then just was like ‘Nah, penta knows what they’re doing’ and clicked accept. If I robot reviewed anything bad it was all my fault 8D
 
maybe I'm making stuff up, you never know...

And with that and quarter to five a.m. I’m off to bed o/
 
4:05 AM
@M.A.R. I originally wanted to write an answer to that, but I was too busy. Let me see if I can write something today, if not go ahead with whatever you deem fit.
You could wait until the pin (in chat) expires. I think that's two weeks, I usually find that a sufficient time to move along. Shouldn't take too long now.

Handing @Jan a review suspension
@Jan It doesn't notify you of negative rep changes. Clicking the dropdown would've fixed it.

meh, don't really like any of the answers on the question i bountied
if I had to pick one, I'd go with Dave's answer, but to be honest I understood nothing after reading it.
the other one is just rambling and I tried my best to parse it, but the argument doesn't convince me at all ("lanthanum fills 5d to allow the rest of the series to fill 4f")

@M.A.R. I know. Only I forgot to click the dropdown that time ;)
@M.A.R. Huh?
 
2:29 PM
@orthocresol Seems to me there's never really a very satisfactory answer to "why does element X have electron Y in subshell Z?" sorts of questions.
"That's the way the quantum mechanics works out (to the best of our ability to determine)"
 
3:27 PM
@hBy2Py You're right. Still, sometimes the inorganic chemists have managed to come up with back-justifications that somewhat make sense, I was just hoping for one :D
Usually something along the lines of shielding, penetration, and effective nuclear charge.
I actually tried to take a look in the library. There was some useful stuff but I didn't write an answer since I didn't have much time. It wasn't particularly convincing either.
Or perhaps I was just too stupid to understand it ;)
Nadine strikes back

@orthocresol His new avatar looks more like algae. I like it
 
@Martin-マーチン What do you 'computational chemists' do? (I always wondered actually ._. )
@M.A.R. o/
 
\o
@AaronAbraham compute things obviously
 
-_-
How'd that make them any different from accountants then? O.o
 
Because they compute things using computers and the things they compute is not people's money.

Is Iran dusty?

@AaronAbraham Hmph?
 
Just curious ;P
Anyhow, bye o/

Q: What happens when prop-2-en-1-ol reacts with concentrated hydrogen bromide

olympiad mathWhat happens when prop-2-en-1-ol (allyl alcohol) reacts with concentrated hydrogen bromide ? My Idea: I thought that in the first step protonation of the hydroxyl group will take place followed by formation of a carbocation. Then the attack of bromide ion from hydrogen bromide takes place and t...

SciFinder disagrees with that person’s exam. Should we be concerned?
 
Meh, a lot of things disagree with a lot of things but we're not concerned.

A: Policy on AMIRITE questions

Martin - マーチンTurn them into canonical questions, close as duplicates. I personally am not a big fan of these kinds of questions, as they basically already violate our homework policy, which clearly states that a question shall be conceptual. (One of the points I would like to highlight in a revised version.)...

BTW giving this more visibility.
I like controversies
 
Jan
@M.A.R. I would have stumbled across it tomorrow anyway, but it doesn't hurt to upvote it now, does it? (I approve of the idea!)
 
Zhe
@Jan I thought hydrobromination was anti-markovnikov under normal conditions
Presence of peroxides or something like that
With the radicals present, it's the bromide radical that attacks so the selectivity is reversed from protonation as the first step
 
Jan
4:49 PM
@Zhe No. Please go and look up Markovnikov's rule again. It was originally made for cases like hydrobromination, where HX adds to a double bond. No need to invoke peroxides or anything.
 
Zhe
I just did
And I'm semi convinced I'm right :(
Trying to find a suitable reference
Not "organic chemistry portal"...
 
Jan
In organic chemistry, Markovnikov's rule or Markownikoff's rule describes the outcome of some addition reactions. The rule was formulated by Russian chemist Vladimir Vasilevich Markovnikov in 1870. == Explanation == The rule states that with the addition of a protic acid HX to an asymmetric alkene, the acid hydrogen (H) becomes attached to the carbon with fewer alkyl substituents, and the halide (X) group becomes attached to the carbon with more alkyl substituents. Alternatively, the rule can be stated that the hydrogen atom is added to the carbon with the greatest number of hydrogen atoms while...
@Zhe Are you now …?
 
@Jan time of day... Lol... I'd do any of this, or all of this any time of day
 
Jan
@Martin-マーチン But you know:
 
Zhe
Ugh, what are the conditions for that reaction?
See, I thought you had to be extremely careful about removing oxygen and any trace of peroxides or it would add anti-Markovnikov
There's a famous paper on this :(
 
4:54 PM
@Jan .... Austrinken!
 
Zhe
Sorry, my workstation is flipping out because I'm doing a big compile
Trying to find this without Chrome freezing up on me
 
@M.A.R. how is that controversial? I'm just using your idea
 
Jan
 
Zhe
Looks like I learned the history wrong :(
Time to rewrite that portion of memory
 
@Zhe I recommend removing everything before rewriting any... Alcohol usually helps lol

Oh it does....
I'm currently watching bones.... I do that because I am very amused by the scientific stuff they can do within minutes
 
Jan
Took me a while to realise you're not talking about skeletons.
 
which can't do anything within minutes...
 
Haha.. yeah, the TV series
 
Zhe
d'oh I needed to restart my workstation, and now it wants to install nvidia updates :(
 
Tomorrow is a holiday, caught me by surprise so I'm enjoying to watch stupid stuff
@Zhe it's a conspiracy

Q: Do electrons in an atom revolve around the the nucleus clockwise or counterclockwise?

userDo electrons in an atom revolve around the the nucleus clockwise or counterclockwise? Is there any rule to determine?

 
Jan
@Martin-マーチン I thought that only happens if somebody from Lower Saxony leaves Lower Saxony =O
 
Zhe
@Mithoron Niels Bohr has a lot to answer for... >:-O
 
@Zhe Not really
 
5:11 PM
@Mithoron nice calm answer, good one!
@Jan sorry, I don't get that
I'm so glad that they updated chat... It's so much better now
 
@Martin-マーチン It was annoying me for some time
 
Jan
@Martin-マーチン What did they update?
 
Is it like debunking of debunking now :D
 
Jan
It's such a bad idea to go from Bavaria to Lower Saxony …
 
@Jan a while ago they updated the mobile page... Should have said I'm on my mobile, because I'm in bed and to lazy to get up
 
Jan
5:16 PM
Oh! Yeah, you're on mobile a lot which I am never. (Although that might change after Christmas; we'll see …)
 
@Jan only when drinking booze
So like.... Always
 
The old quantum theory is a collection of results from the years 1900–1925 which predate modern quantum mechanics. The theory was never complete or self-consistent, but was a set of heuristic prescriptions which are now understood to be the first quantum corrections to classical mechanics. The Bohr model was the focus of study, and Arnold Sommerfeld made a crucial contribution by quantizing the z-component of the angular momentum, which in the old quantum era was called space quantization (Richtungsquantelung). This allowed the orbits of the electron to be ellipses instead of circles, and introduced...
 
Zhe
@Mithoron I was just kidding
It's much more of how chemistry education is set up
 
@Jan 16 in Japan 😀
 
Zhe
We teach the Bohr model as much more than a model
And then we get this kind of confusion
 
Jan
5:20 PM
@Martin-マーチン Any ones that always fall on a Sunday?
 
@Mithoron I remember that we talked about a tag for that
@Jan if a holiday falls on a weekend, it's repeated on Monday
Okay.... Time to retire... See y'all soon
 
Jan
@Martin-マーチン I want to go there. Even more now.
 
We have a lot less holiday though
I downgraded from thirty to ten days
 
@Martin-マーチン These are among the Unicode chars I hate most
 
what, doesn't Windows support emoji?
 
5:27 PM
Sorry... My phone was that
Okay... Afk now
 
@pentavalentcarbon No, it's so damn small that I can't recognize whether Mart was eating a bar of chocolate, being furious, worried, crying or has an adhesive bandage instead of a mouth
 
Jan
@M.A.R. That's okay, I see a square with 01F600 inside it.
 
@Jan I knew you Germans named everything instead of loving it but this has gone way too far
 
Jan
@pentavalentcarbon 01F62E
 
5:31 PM
all I hear is whining that "my operating system doesn't support unicode emoji"
though I still don't have the font situation worked out on some of computers so...
I'm a hypocrite
 
Jan
@pentavalentcarbon I think it's the old Firefox that I refuse to update on my work PC.
 
A very likely cause, I know early Chrome versions had that problem too.
Even though there was OS support.
 
Jan
They'll probably work fine at home on an updated Firefox, made useable again with a gazillion add-ons that should be part of the initial shipping */rant*
Awww, no fun @ortho! I was looking forward to another late answer review D=
 
@Jan oops..
I'm too efficient ^^
 
Ah, you're one of those...
an add-on fiend
 
Jan
5:38 PM
Can I retract my mod vote?
 
@Jan looks for suspension button
 
Jan
I don't have a problem with add-ons per se. But I have a problem if 1) important (in my eyes) features of the program are removed and have to be re-added with add-ons (status bar) and 2) if the design gets destroyed completely making everything unfindable with no way to revert to default behaviour without an add-on. And note that Classic Theme Restorer almost seems like a larger add-on that the entire firefox engine */rant²*
 
I agree. I got rid of CTR once I decided it was slowing everything down. And the Safari and Chrome-style bar that appears when you hover over a link is enough for me. But they have consistently shown that they don't listen to what the users want.
 
@Zhe Yeah I get your point
 
They consistently treat users like idiots. But the other browsers still manage to be worse.
 
Jan
5:50 PM
*pipes comment to Mozilla foundation*
 
nah, they don't care. They'd rather think we want to use Hello and Pocket.
 
Jan
There should be some open source project taking a good old™ Firefox release as a starting point and patching bugs/closing vulnerabilities/including backend features thenceforth. That might be the correct threat to Mozilla …
 
I know that Waterfox and Pale Moon exist, but I think they're for Windows only, and they're always going to be behind.
I don't know anything about the Mozilla open-source community but I suspect that the number of non-Mozilla people who are capable of contributing to Firefox or its forks is very, very small.
So unfortunately I don't think that's going to happen.
I accepted several years ago that web browsers are always going to be the absolute worst applications on my computers. They're terrible.
Part of this is the web's fault. Too much stuff is this garbage dynamic JS that just murders performance. Everything feels slower now than when I had a 56K modem because designers do whatever they want.
 
Jan
Yeah … not even word processors have to cope with so many different documents from so many different sources adhering to so many different existant or inexistant standards …
 
Example: MathJax is just brutal on Firefox Nightly. Better on Chrome, but not worth it for me.
 
Jan
6:05 PM
And everything else that interconnects millions or billions of people just forces their standards upon you like chat programs.
 
Argument against your point about word processors: I think they've gotten slower too.
chat...don't get me started on chat
 
Jan
Tbh I wouldn't know … I started transferring over to TeX completely.
 
Yes, but we have collaborators who force us to use Word. And they're computational chemists! It boggles my mind.
Otherwise I haven't used a word processor in 5 years.
Software has become way too complex and slow for reasons I still don't fully understand. Relatively speaking my 266 MHz Pentium II running Windows 98 was faster at some things.
 
Jan
Would the following reason suffice:
> OMGlolz I can do THA THINGZ!
 
Yes and no. I mean, I feel like for the most part I'm a pretty standard computer user.
I want to browse the web, read PDFs, organize my photos, listen to music, sync with my phone...
 
Jan
6:10 PM
That was the developer's perspective ...
 
Then definitely yes.
I'll stop now, but yes I do have very strong feelings about this
welp, now I have to convert a Markdown file to Word so our collaborators can view it...
 
Jan
Send them the PDF =D
 
I do that with my boss sometimes. Works great.
also I can tell what you're doing right now hehehe
btw tell me if my edits are bad
 
@pentavalentcarbon shouldve flagged that
 
Jan
Damnit, my cover blew again!
 
6:17 PM
eh, I kind of disagree
more complicated that most of the hw questions we get
also sometimes \left( and \right) make things harder to read/look weird

which question are you all talking about?
 
o.o

chemistry.stackexchange.com/posts/62057/revisions
 
don't feel like it matters. this guy has a history of meh questions
 
6:20 PM
In that case I will agree with you, I didn't know that
 
Jan
Consider every question on its individual merits.
 
Well then now I disagree!
 
no no
 
AAAAAHHHHHHHH
 
Jan
Only if the individual consideration leads to a bad question and the OP has a history draw conclusions.
 
6:21 PM
yeah, Jan is correct
 
Jan
(Yes, let's continue confusing him! e.e)
 
I didn't mean to say that you shouldn't edit it
I meant more like it's probably gonna go to waste
lemme leave a comment, i'll leave it to you guys to VTC..
 
I have plenty of edits that have gone to waste, it's fine, they only take a few minutes of my time
(maybe that's why I get nothing done)
 
if he edits the question, then it won't be wasted :D
 
Jan
@pentavalentcarbon Ah yes, my problem indeed. Sitting on SE rather than working on my thesis ^^'
 
6:25 PM
It didn't need to be rolled back...
 
i rolled back to take a look
 
I'm gonna add your comment to my Markdown file of template comments, I like this one
 
6:26 PM
yup, I like this one, actually in general I try to refrain from mentioning the word "homework"
because that can sometimes lead to people saying that it's not their homework
oh well, time to make dinner
 
Jan
And with that, I'm going to shut down stuf fat work and go home. o/
 
and few people like having words put in their mouth

@Jan I was wondering why your work was fat.

Are you yes?
 
No, I'm excellent
 
Do you think it would be helpful to have chat sessions?
especially to discuss site policy
 
About?
Well, yeah sure.
I'm pretty sure most of the people will need will show up.
 
Physics did it yesterday, so I was thinking about it.
 
6:43 PM
And the ones that don't or can't can follow the results through a meta post and not get any headaches
 
The hardest part is ofc finding a good time.
 
No it's not. You can use the TRE II proposed times
And you can ask!
 
Yeah, certainly.
 
Informing people of a future chat session with a featured meta post is a pretty good idea

A: Drinking 18 M-ohm water

user36929Would they immediately die? No. I agree, no. But if long time drink pure water, such as 18 M-ohm water, it could cause shortage of u-elements, such as Zn, Se, Fe,..., even all those very,very small quantity, but important for the life, the health... Normally speaking, drink normal water is the...

> Normally speaking, drink normal water is the best.
that's catchy enough to be an advertisement slogan
 
wth is "M-ohm"?
 
@pentavalentcarbon A proudly pronounced ''mom''
 
TBH I don't know
 
this site is full of questions like that
the ones mentioned in the "flamethrower" meta post
 
It is?

I think so
 
@pentavalentcarbon Which?

Q: How many shots will it take me to kill you with a neutron gun?

M.A.R.Recently, I've seen a trend of $\mathcal{\color{red}{SCARY}}$ questions back on chem. They're mainly about this: Get the picture? No? OK, I'll be more straight-forward 1: How to dissolve fifteen elves and seventeen trolls ASAP? How much does it take to dissolve an angry bird with hydroc...

 
I think the fact that we don't know what 18 M-Ohm means
probably indicates that it's something to do with pseudoscience
 
and actually, I think we are wrong
 
6:53 PM
18 molar, resistance...something?
 
It's the resistivity of deionised water
So 18 MOhm = 18 x 10^6 Ohms.
 
ok, do you want to edit it, or me, because it is not worded properly
 
It might be a good idea to make a mention of it in the question
You can go ahead. I need to pay attention to the spaghetti
 
7:21 PM
@Jan really?!?!
Boy, those Germans sure are exacting and precise.
 
Jan
Course we are ;)
 
My PI has become too Americanized, then.

I spareth your life
 
Jan
Once you’ve finished dealing with your spaghetti, @ortho, I have a flag for you to attend ;)

meh
I'm inclined to just delete both his answers because they're factually incorrect.
But I'll stick to downvoting.
 
@orthocresol DECLINE JAN'S FLAG DECLINE JAN'S FLAG
 
Nah.. the flag was telling me that he posted a second answer
 
Jan
I was once told that if it can be seen as an attempt at an answer, never delete just downvote. So yeah, that's what I did.
 
You're absolutely right.
Well, to be fair, we delete VLQ answers even though they're attempts at answers. But factually incorrect isn't VLQ, so..
 
Jan
Would’ve been funny if you had deleted the higher-score answer and edited the earlier, lower score one and then dropped an additional downvote or something … but seems like its our two downvotes they’re suffering from.
