seems he got upset with being downvoted, so now every comment/answer is in caps lock..
:(

@orthocresol I noticed the same thing. I might need to step in, but I want to give him time to calm down.

Hm, each time I try to work on a post today, it is answered, edited, or deleted by someone else.
 
12:17 PM
@Mithoron I disagree, the history of science is at worst, interesting, and we don't learn enough about it in school.
The second one in particular is really good, I recommend it.

@Loong Rough time lately :(
 
vacations are over
 
Yeah
 
3:41 PM
@Loong Hmm, why is Dissenter giving absurdly big bounties? Max is for him standard
 
3:53 PM
@Mithoron Dunno, he always places really large bounties.
 
@orthocresol Guess he doesn't care about rep, but still it doesn't seem reasonable
 
@Mithoron Whatever he is happy with, I guess.
As for me, I am greedy for rep.................

^^
 
If not these bounties he would have more rep than you ;)
 
Indeed, he has good questions after all, I have so few questions
 
@orthocresol Lots of questions :D
 
4:02 PM
whereas I would estimate our answer scores to maybe be the same order of magnitude
I just thought of something. If another user and I repeatedly place +200 "reward" bounties on each other's answers, then award them... Does that mean we will both get the Epic and Legendary badges faster? (200 daily reputation 50 and 150 times respectively)
pings @Jan
 
@orthocresol I think it only counts rep from votes
 
Oh ):
No!

Q: Mortarboard badge awarded in response to receipt of bounty

Alison R.I got a Mortarboard badge due to a bounty I received today. The definition of the Mortarboard badge is to have gotten the max rep for one day, but the FAQ states that bounty does not apply to the 200 daily rep limit. So technically, I haven't reached my daily limit, yet I still got the Mortarboar...

 
Do we really consider such questions about ChemDraw on topic?
I am asking because I prepared a similar answer on how to draw ferrocene.
And now I don’t know what to do with it.
 
@Loong I can't find any precedent where anybody said it was off-topic
 
@Loong It seems borderline
 
4:12 PM
The problem with the question is, that it becomes a software issue, that might have a very specific solution. Support might be the best option there. However, as it is working with my version and you have a newer one, I suppose it should work with yours, too. You can find me in Chemistry Chat to talk about it. Have you ticked "File > Preferences > Building/Display > Automatic Atom Label Alignment"? Have you tried entering "OH" instead? — Martin - マーチン ♦ Apr 20 at 7:55
 
Bye, BBL

I can see one close vote "I'm voting to close this question as off-topic because it's about how to use software." in the past 90 days; but I don't know the question.

Q: Are [software] questions on topic?

ManishEarthSparked by this question. Should software questions be on-topic? They aren't exactly expert-type questions. They're something which chemists know about, but unrelated to chemistry concepts. They can get good answers here--but are they good for the site? Physics seems to allow them, though I per...

However, this was inspired by a question on software recommendations.
 
I started drafting a meta question about what belongs in .
Never got around to finishing it.
IMO they should be allowed but without an expectation that they'll get answered.
 
Jan
@orthocresol Yes, that works. It’ll get you reported to the mods pretty quickly ;)
 
4:23 PM
@Jan B-but I reallyyyy like your answers...
`(.•.)´
 
Jan
@orthocresol I reallyyyy wanted to star a seal again *___*
By the way, in recent times I tend to have given away bounties in a liberal fashion to prevent my chemistry rep surpassing my German rep xD
 
@Jan Why'd you want that?
 
Jan
@orthocresol Because I'm more German than chemistry? I dunno …
 
@Jan Sound reasoning, now all I need is a seal.SE.
Every question will be "`(.•.)´?"
And every answer will be "`(.•.)´".

That's it. I quit!
 
The Lord Privy Seal (or, more formally, the Lord Keeper of the Privy Seal) is the fifth of the Great Officers of State in the United Kingdom, ranking beneath the Lord President of the Council and above the Lord Great Chamberlain. The office is one of the traditional sinecure offices of state. Originally, its holder was responsible for the monarch's personal (privy) seal (as opposed to the Great Seal of the Realm, which is in the care of the Lord Chancellor). Today, the holder of the office is invariably given a seat in the Cabinet of the United Kingdom. Though one of the oldest offices in government...

@Loong So his new name is @ortho­privy?

@ortho 1:30 a.m.? You’re ‘back home’ then?
 
That was really stupid of me.
Yeah, I've been back home since mid-Aug. Back to UK at the start of Oct...
 
Jan
Oh, okay ^^ (Which part was stupid; mentioning your timezone or the wrong example? ;))
 
The wrong example of course haha
 
Jan
Gotta see if I can get my introduction written before you go back to the UK. Probably won't, though ^^'

Q: Why is this question not overly broad?

JanThis question was posted 2 days ago, closed yesterday as being too broad and reopened today. The question has never been edited so its contents are the same throughout. I wonder why people voted to reopen it and why that vote subsequently went through. The question asks whether there is a chemic...

Q: Why alkene isomerization does not occur

vin2I have an organic chemistry question. It states: The mathematical form of the four $sp^3$ hybrid orbitals are given below. a) $sp^3 = 1/2s + 1/2p_x + 1/2p_y + 1/2p_z$ b) $sp^3 = 1/2s + 1/2p_x - 1/2p_y - 1/2p_z$ c) $sp^3 = 1/2s - 1/2p_x + 1/2p_y - 1/2p_z$ d) $sp^3 = 1/2s - 1/2p_x - 1/2p_y - 1...

Is the title related to the question?
 
@Loong well, not really...
Or was it a rhetoric question? ;)
 
@Loong terrible latex
 
@Mithoron I could have missed something.

A: Naming of 2-methylpropane

bonYou are correct. It is unnecessary to include the 2 in order to provide an unambiguous name. This compound is also often called isobutane which is an older name that is still in common usage.

Are there any relevant IUPAC rules on this? — matt_black May 29 at 22:22
(that's my question)
if nobody ain't gonna answer then i'll ask it on main lol
 
@user34388 According to the current IUPAC recommendations, the preferred IUPAC name (PIN) is 2-methylpropane.
In general nomenclature, however, locants are often omitted when there is no ambiguity.
The recommendations for PINs also include some rules for the omission of locants, but none of them apply to the locant '2' in 2-methylpropane.
 
11:08 PM
@Loong what locants for example? hexan-1-oic acid?
 
@user34388 Yes, the PIN is "hexanoic acid".
 
what other locants?
 
The trivial cases:
substituted mononuclear parent hydrides
 
also, what does the systematic iupac name say?
 
@user34388 hm? The systematic name for what?
 
11:14 PM
for 2-methylpropane
also you may continue
 
other trivial cases: monosubstituted chains of two identical atoms (e.g. ethanol, not ethan-1-ol)
However, if you need a locant for a second substituent, you also have to include the first one (e.g. 2-chloroethan-1-ol).
 
in the pin? because i saw 2-chloroethanol
just like 2,4,6-trinitrotoluene
or 2-chlorocyclohexene
 
@user34388 Yes, the PIN is 2-chloroethan-1-ol. In general nomenclature, you may use 2-chloroethanol.
 
oh, please continue
 
@user34388 That PIN is now "2-methyl-1,3,5-trinitrobenzene". However, you may still use "2,4,6-trinitrotoluene" in general nomenclature.
@user34388 And that would be "1-chlorocyclohex-1-ene".
!!img/1-chlorocyclohex-1-ene
 
11:25 PM
 
oops, my mistake
@orthocresol
would its pin be 2-methylphenol?
oops i accidentally pinged
!!img/orthocresol
 
Hold tight, I'm processing your request ... ╰( ^o^)╮-=ニ=一=三
 
@user34388 Yes, 2-methylphenol is the PIN.
@Chemobot ?
The locants are omitted when all substitutable hydrogen atoms have the same locant (e.g. "trifluoroacetic acid" not "2,2,2-trifluoroacetic acid").
!!img/trifluoroacetic acid
 
!!img/orthocresol
 
11:32 PM
 
!!img/ortho-methylphenol
 
!!img/ortho-hydroxytoluene
 
The locant is also omitted when there is only one kind of substitutable hydrogen for monosubstituted symmetrical structures.
!!img/pyrazinecarboxylic acid
 
11:36 PM
 
!!img/pyrazinecarboxylic acid
 
i see
 
The PIN is pyrazinecarboxylic acid, not pyrazine-2-carboxylic acid
 
carboxylic acid??
!!img/pyrazine
 
11:38 PM
 
hexanecarboxylic acid anyone
when is "carboxylic acid" used?
 
@user34388 when the C of the -COOH group is not part of the parent structure (e.g. the longest chain)
!!img/cyclopentanecarboxylic acid
 
!!img/NC(=O)CC(=O)OH
 
11:41 PM
what would this be named?
 
3-amino-3-oxopropanoic acid
 
!!img/PhCH3
 
@Loong the amide is gone?
 
@Chemobot ?
 
11:43 PM
wow chemobot doesn't know abbreviations
 
@user34388 the acid wins
 
!!img/AcCl
 
No result found.
 
@Loong what happens when the acid loses?
!!img/cyclopentanylmethane
 
11:44 PM
!!img/cyclopentanylmethanoic acid
 
No result found.
 
how to name self-esters?
eg ester of this:
!!img/5-hydroxypentanoic acid
 
@user34388 acids usually win because they have a high seniority
 
!!img/C1(=O)OCCCC1
 
11:46 PM
 
@user34388 The lactone?
 
no systematic naming?
is this the pin?
 
Lactones are usually named as heterocycles.
!!img/oxan-2-one
 
!!img/oxane
 
11:48 PM
 
!!img/oxane
 
no systematic naming?
!!img/C1OCCCCCCCC1
 
No result found.
 
@user34388 That is a systematic name. It's just another system. ;-)
 
11:49 PM
how would C1OCCC1 be named?
 
!!img/oxolane
 
what is the system???
!!img/2-oxolanone
 
!!img/bicyclobutane
 
11:52 PM
 
@user34388 Hantzsch-Widman system
Hantzsch–Widman nomenclature, also called the extended Hantzsch–Widman system, is a type of systematic chemical nomenclature used for naming heterocyclic parent hydrides having no more than ten ring members. Some common heterocyclic compounds have retained names that do not follow the Hantzsch–Widman pattern. Hantzsch–Widman nomenclature is named after the German chemist Arthur Hantzsch and the Swedish chemist Oskar Widman, who independently proposed similar methods for the systematic naming of heterocyclic compounds in 1887 and 1888 respectively. It forms the basis for many common chemical names...
 
Was?
 
!!img/1,3-dioxolane
 
oxirane, oxetane, oxolane, oxane, oxypane, ... :o
oxipane*
