@Tanuj maybe, I am not really sure of it...

@Zhe how feasible would it be that oxygen would lose an electron to form O+ ion, given that then O would attain a stable half-filled orbital configuration? I was wondering that O+ is really uncommon, so that is probably unfeasible

@ApoorvPotnis i'm not talking about forced condition but favorable condition. That IE is probably being measured under forced conditions

@AvatarShiny why'd you delete that question?

@GaurangTandon Yeah. I was talking about forced conditions. I have no knowledge of $\ce{O+}$ in reactions.

@GaurangTandon It's all relative. No reason why it shouldn't just steal back an electron from something else immediately

@Zhe oh that's reasonable

@GaurangTandon I'll undelete it

@AvatarShiny yeah please don't be so quick in deleting questions; it hadn't been even a day; i was also interested in the answer

Undeleted

Honestly I never get answers for questions like these

@AvatarShiny you mean they usually go unanswered?

Last time for my EAS one I put a bounty 2 timee

Then got a somewhat useful comment

don't worry too much

as long as the question is there

someone might find time to answer it

3/6 of my latest questions have 0 answers and >0 score

and are relatively less conceptual than the one you asked

still no answer

even I sometimes wonder why this is so

there may be a dearth of good new questions, but there's always some nice questions that have been asked before but are unanswered

people should answer them

but maybe they get bumped off the homepage

or whatever

That's true , all of that

I'll bounty it

Let's see

i'd say you wait

at least a week

before bountying that multi-annuli question

@GaurangTandon I can't put one yet :P

oh ok

@Abcd look at my latest edit on your Q chemistry.stackexchange.com/q/91156/5026

apparently, there's a problem at 4-iodophenol, the acidity order is discontinuous :(

that might make it even harder to predict the answer theoretically

@ApoorvPotnis you are aware that they've explained (on the internet) the opposing order through basicity right?

@AvatarShiny Yep. Solomons also explains by the basicity oeder

hey did anyone understand why fluorine cannot undergo finkelstein reaction chemistry.stackexchange.com/q/6948?

i need help, please

@GaurangTandon Fluorine is a very bad leaving group.

?

Bond enthalpy ?

@AvatarShiny yeah that could be; but neither answer mentions this though :/

besides, what is Klaus' answer trying to convey; I don't think if he even answered the question correctly? chemistry.stackexchange.com/a/7799/5026

I will give a take on the EAS, I'm a bit buried by work sending a paper but this week should be ok

@Jojostack great! :D

can you send me the link ? So I will put in my bookmark

thanks

avatar eventually answered it himself though

@GaurangTandon ok I will check it thanks :)

though you might definitely wanna have a look and suggest an answer covering more things he left out just in case

@Jojostack welcome :)

@Jojostack That would be great as my answer is not based upon any literature . I really look forward to finally getting an answer from credible sources.

@AvatarShiny Can you tell which question this is from MS Chouhan? chemistry.stackexchange.com/q/88067/5026

Guys , how do I compare the critical temperatures of NH3 and H2O ?

What's the current best practice for inserting a footnote? HTML/Markdown/MathJax are all acceptable. Worse case I could just use \tag and \eqref...

I understand that the different SE/SO sites have different needs, but the lack of consistency for such a simple requirement is bad design

@LinearChristmas Regarding the question: Is there a performance difference between \pu and \mathrm. Yes, there is. Ater all, \pu is doing some parsing. But it should be neglectable. It should be less than 100 ns. I.e. 10 occurances would have an overhead of 1 ms. Nobody would notice. (It's hard to properly measure such things. My measurement comes from 50000 usages of \ce. My feeling was that the garbage collection has most impact on the running time, not the CPU usage itself.)

Regarding the question whether to use \pu instead of \mathrm, I'd kindly ask to use it only for numbers and/or units. And I'd strongly advice against mis-using it for more than pure letters. Everything that goes beyond pure letters might get rendered differently, in future. For instance, m2 rendered differently in earlier versions. And the rendering of kg.s will change shortly.

Regarding the question whether \mm or \mr could be created as a shortcut for \mathrm. Yes, they could. It's as easy as typing \let\mr\mathrm. And it's a little bit more complicated to do that in a MathJax extension. But one has to be careful not to create side-effects.

I already thought about a C.SE extension for MathJax. You could discuss features and I could create it. If everything works perfect, the C.SE extensions become the de-facto standard that people want to use everywhere (like amsmath). But there is also a good chance that C.SE becomes a more and more closed community ("They even have their own flavor of LaTeX").
