Gamification works so well that I just waited until the UTC clock hit 01:00 before posting my question on German Language — even though I already have the Hatter on German.

Oh Jan. That question.....

No no
It's a great question
Though don't forget about Geissler (sp?)

Geissler …?
Did you find another one of those gaping holes in my Swiss cheese of knowledge about mechanisms and name reactions …?

@Jan Was a question closed while you were writing an answer?

Quite a few recently.
One was the newest post on meta.German, which Wrzl dupehammered while I was writing.

Did you check whether the trick using the browser console to reenable the "post your answer" button on the client-side still works?

I don’t know that trick.

Ah, ok. ;-) So I don't follow your conclusion "this can no longer happen" yet.

Well, I’ll try and remember to tell you if I’m about to drop the fifth close vote on a question that you can get ready to post an answer ;p

@Jan I have just tested it. It still works.

Ah well, downvote my meta post to -3 then so I can win a badge instead =)
At least I have my Hatter now =3

Q: modern open-source tools for simulation of NMR spectra

Curt F.I am interested in predicting the NMR spectrum of small organic compounds. It doesn't matter to me if the prediction is very accurate. I'll eventually be comparing prediction to experimental results. It looks as if several free online tools offer the ability to do such predictions: NMR DB is...

@Jan I'll help you, but it's already difficult enough to get people to vote, let alone reverse their votes (or give a chance to something that's -2).
As such, that's one of the hats that I think will be very difficult to get.

@user123733 count the 1s electrons for b, and count the 2s and 2p electrons for a
and subtract 1 electron; this is the electron that is observing the calculated effective nuclear charge

Q: How to relate a reaction barrier to the time the reaction needs to proceed?

Martin - マーチンAs I am writing this I am at a conference and one of the participants just asked a question where he linked reaction barriers to durations for the reaction to complete. To paraphrase: From our experience a reaction with an activation barrier of 15 kcal/mol should occur instantaneous at room t...

@hBy2Py It can't be that bad..
I find it somewhat important to know how to go from one end to the other...
and I have never written a bachelor thesis... so i don't really know what kind of effort this is
also @hBy2Py did my edit destroy the answer already given?

Blanc chloromethylation
The Blanc chloromethylation (also called the Blanc reaction) is the chemical reaction of aromatic rings with formaldehyde and hydrogen chloride catalyzed by zinc chloride or other Lewis acid to form chloromethyl arenes. The reaction was discovered by Gustave Louis Blanc (1872-1927) in 1923. The reaction is performed with care as, like most chloromethylation reactions, it produces highly carcinogenic bis(chloromethyl) ether as a by-product. == Mechanism == The reaction is carried out under acidic conditions and with a ZnCl2 catalyst. These conditions protonate the formaldehyde carbonyl making the...

A: Mechanism for chloromethylation of benzene

MithoronThis reaction is chloromethylation, similar to Blanc chloromethylation, but using $\ce{AlCl3}$ as co-catalyst instead of $\ce{ZnCl2}$. These are reactions belonging group related to Friedel-Crafts reactions but characterized by usage of protonation instead of coordination with molecular Lewis aci...

@Martin-マーチン Destroy might be too strong a word, but you did post facto add a declaration more-or-less specifically saying that what DSVA laid out in his answer wasn't good enough to satisfy you.
If I'd come across this sort of thing in the review queue, my recommendation would've been to accept his answer, then post a new, follow-up question. "In this linked question, such and such answer was given about the Eyring equation. How exactly is the Eyring equation used to justify these sorts of estimates etc. etc.?"
And then, probably recommend editing the original question with a link to the new one: "A follow-up question asking for a more detailed exposition can be found here (link)"
It spreads the content around the site more, but it avoids the "post facto edit sabotage" of the sort DSVA is unhappy about.
IMO, the former is the lesser evil. Not sure what the mods'/site's/SE's official stance is.
As for the 'Bachelors thesis' bit, I hadn't fully read the comment chain under the post.
Afte reading this comment, I retract my statement (and delete my comment) to that effect. I hadn't realized you were just looking for, e.g., an example calculation using the Eyring equation. I read it as you wanting a much more elaborate/detailed investigation of transition state dynamics/statmech/etc.
Partly, too, your bounty message is kind of misleading:
"A good answer should go beyond the Eyring equation and include some authoritative uses/references of the model."
You may have meant "A good answer should go beyond simply referencing the Eyring equation and ...", but that's not how it reads.

@hBy2Py awww, I don't like that you can't edit these things.
Yeah, since I was on a conference I missed editing in the comments. And I think the question was clear enough that I wanted an actual connection between the numbers and the time, but I'll read it again tomorrow and might roll back about accordingly. I'm too tired now...

@Martin-マーチン <nod>, I understand why the Overlords have bounties structured with ~everything being "THERE IS NO TURNING BACK"... but it's brutally unforgiving in some annoying ways at times.

@Martin-マーチン you can refund and re-place the bounty, "mod abuse" but I think if the intention is OK, then no big deal...
(Might be a bit different in this case since the bounty has been up for a day or so though...)

Right I could do that, probably would consider that when someone asked for it via flag.
Thank y'all for looking into that
@orthocresol I can pay a higher bounty making up for that. After all bounty is about visibility
And since my last two bounties lead nowhere, I really want to award one...

@paracresol I remember somebody proudly telling me they got it in another castle chatroom ;p
That moment when you look at an unfamiliar avatar and your first question to yourself is: ‘Which hat is that?’
Then, when you open the userpage, you see that the hat is part of the avatar itself … xD
