Bad bot. :|

TRY HARDER!

No qchem qs today. Boring... :|

@Wildcat Answer this one then. Guaranteed to be interesting!!11!!11elevenone.

Boring!

I know why I got so many upvotes so quickly! It's a HNQ.

I have the feeling that there are never less than two Travel questions in the HNQ …

It used to work.

@Hipp probably never changed it =C

Come to think of it he hasn't been here in quite some time.

He is?

He still haven't made chemobot throw up some Zalgo.

Yay! Finally finished this...

@orthocresol Regarding this, I think we should gather this and a bunch of others, and make some others or make you make some others, and tag them with [canonical]. Then we'd have an efficient, handy, and compact lil' weapon to shoot at the dupes.

Alert! Alert! Meta tag!

Of course the labor is on you but for some reason I believe you'd enjoy it.

Loong has the unenviable task of the nomenclature ones.

@orthocresol The tag isn't a big deal really, but it'd make searching easier. And it'd be more bureaucratic.

I believe he'd enjoy it too

Chemists are masochists

@Rubisco is a chemist.

I've just been quite free recently, so decided to write up some canonical answers.. University term is resuming real soon, unfortunately.

@Rubisco is a masochist!

:O

There's only one thing Mart loves more than he hates meta tags. And that's bureaucracy.

He can't help it. It's in his blood.

@Wildcat I . . . for some reason can't argue with this

And we all live to appease lord Mart the great

I wonder what are my chances if I run in the election

With a not-handsome rep.

But a lot of trash talking

I'd say, pretty good. You'd win by default.

And fights in meta

@orthocresol I'd like to doubt it. I don't think I'm really popular

@Rubisco There's nobody else running :D

And review pointz™

@orthocresol YOU CALL YOURSELF NOBODY ELSE?

Don't make me chase you with a harpoon

I did think about it, but there's several reasons against.

@Rubisco well, now you have the opportunity to find out

It's a trap!

sobs

Question banned for life. Better make a new account...

@orthocresol I will just copy the entire Blue Book into one self-answer and close all other nomenclature questions as duplicate.

@Loong But you won't be enjoying that. Your computer would even less.

@Loong Whatever question that is, I am voting to close as too broad...

> ppl hw cn i lrn iupc nams

name all the things

That guy quit SE to come up with witty tweets

Loong is secretly our comment feed.

hm

I just learned that "zenzizenzizenzic" is a word.

@Rubisco Square of Squares Squaredly Squared

@Loong So it's German?

> The root word for Recorde's notation is zenzic, which is a German spelling of the medieval Italian word censo, meaning "squared".

In German, we still have Zinseszins, which is derived from Latin census, but that's a different story.

@Loong So you just omnisciently summoned the data?

Zins is interest (e.g. on investments); Zinseszins is interest on interest (i.e. compound interest)

Hello everyone, I have a question for organist chemist

@Shadock Jello

@Rubisco you're not an organic chemist! :D

I'm not even a chemist

@Wildcat he is a chemist, composed primarily of organic matter, which makes him an organic chemist. ;)

:O

Potential reason I won't be a good mod. No kidding.

At school I have to make the bromation of the anisole using the NBS. The class is divided into three groups and the first has aldreay did it and tomorrow is the turn of my group. In the first group in average the had a yield of 12%. I was thinking if instead of take 1 equivalent of NBS for one equivalent of anisole, if it may be great to use 1.1 or 1.2 eq of NBS ?

@orthocresol lol

@Shadock yeah, might as well

i mean, you would have better luck asking someone who may actually have done the reaction before, they would have a better idea of how much NBS you would need to add to push the reaction.

org syn is somewhat of an art, i guess... so you may as well try 1.5 eq if you like...

@Wildcat alternatively, he is a chemist, who was not sprayed with synthetic pesticides, and was grown in a sustainable fashion... so he is an organic chemist :D

Well I do not want to create other things than p-bromoanisole. I will but I don't want to much. Because I've never used it before.

@orthocresol and also take 1.5 eq of all other educts ;-)

@orthocresol :D

perhaps it is not the NBS, perhaps it is something about the workup.. who knwos

Also to destroy $\ce{Br_2}$ at the end would you prefer to use $\ce{NaOH}$ or $\ce{Na_2 S_2 O_3}$ ?

no clue, i used Na2S2O3 for mCPBA before, but Br2, idk

OK thank's

Eh.. I just noticed something special... Our review queues are empty

What is this ?

@orthocresol Oh no . . . that means I'm out of my job

@orthocresol write a bug report on meta

@Shadock "When anisole and one equivalent of NBS were refluxed in acetone for two hours, 4-bromoanisole was obtained in near quantitative yield."

@Rubisco @Loong That's it, guys, let's pack up. We're not needed here anymore

@orthocresol shit, I still haven't been paid

To a solution of compound 5 (99percent, 108.9 μL, 1.0 mmol) in acetonitrile (MeCN, 2 mL) at 0 °C was added N-bromosuccinimide (NBS, 98 percent, 181.7 mg, 1.0 mmol) in one portion. --> 96% yield (0 deg C -> rt, overnight)

I will do it in ACN like in the publication they gave us. That's why I'm a little bit surprise they got only 12%

Yeah. I find it surprising that you get low yield, which makes me feel like it is possibly: 1) you guys aren't quite letting it run for a long enough time (which is always possible, considering teaching lab timescales); 2) something is going horribly wrong in your workup

In the publication they say only one equivalent of NBS ^^

Mmhmm, most procedures I can find also just use 1 eq.

For the moment it is not my work up ^^

;) All the best.

Ok well I'll try 1.1 eq and I won't say I put 1.1 eq but 1 eq then I'll have a better mark if it works ^^

Hummmm the reaction was stirred during 18h

But we just have 4h maximum for the first part

How long would it take to reduce acetone using NaBH4?

I hope I wasn't too hard on them.

@Jan To err is human. To erf is transcendent.

@hBy2Py ಠ_ಠ

@Loong Will that violate the copyright license terms, though? :-(

@pentavalentcarbon I am in a moods presently, it seems.

@hBy2Py A pdf with 1500 pages that is normally sold at £ 525.00? Yes, probably. ;-)

@Loong Indeed. And, hm. On re-reading, my comment probably read as being far more serious a question than I intended. Ah well.

Has anyone solved the SE for H2^2+?

SE = schrodinger equation

According to MO, C2 has 2 bonds; but it is commonly depicted as having 3?

webqc.org/symmetrypointgroup-td.html

From my understanding, shouldn't the square of the third column be exactly the same with the first column, considering that the square of C2 is E?
