Q: Shouldn’t every question be tagged with its division of chemistry?

Walking through the questions something got me thinking. The tags organic-chemistry, inorganic-chemistry, general-chemistry, physical-chemistry, analytical-chemistry, biochemistry, quantum-chemistry,* theoretical-chemistry* and of course lolic-chemistry seem to be the most general ones we have. E...

Where is everybody D=

@orthocresol Indeed, the avermectins and artemisinin weren't exactly "ready for prime time" in their raw state; some chemical tweaking was necessary for them to be very useful.

Also, there's precedent (e.g. Müller got the Medicine prize for his DDT studies, and Ehrlich got his for arsphenamine).

Meow!

@Jan I'm here! :D

Q: How can I keep my cat off my keyboard?

This is a common scenario when typing: When the family assembled for Sunday dinner, With their minds made up that they wouldn't get thinner On Argentine joint, potato^DR&FTGYB`kuhadrggoy867rt98wouth4bfgdhjlkhdsfghhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhf This happens beca...

@Loong :D

The first answer is ingenious!

Yep, a real "lifehack" :P

5:26 PM

@skillpatrol There is one o.o' So it'll definitely ping.

You do not need it

to get the italic effect

*italic *

:-)

*pats @skill, because he has no idea what I'm trying to do* ;)

5:42 PM

@Jan stop using *italic* type! ;-D

No I shall never stop! *rages*

5:54 PM

So has the details for the second TRE been announced by @inɒzɘmɒЯ.A.M

6:30 PM

Not yet.

inɒzɘmɒЯ.A.M

7:12 PM

@TanMath The next TRE is at 15:30 UTC.

So you're saying we should keep them? ლ(ಠ益ಠლ) On the serious side, we seriously need to introduce a tag for them, or we'll be seriously in serious trouble, seriously. — inɒzɘmɒЯ.A.M 25 secs ago

I love working with @Loong to get to some crazy tag idea.

@inɒzɘmɒЯ.A.M crazy ?

inɒzɘmɒЯ.A.M

@Loong Not terribly descriptive; how about crazy-math-ftw?

7:44 PM

@inɒzɘmɒЯ.A.M Let me check the VIM:

metrology “science of measurement and its application”

(but that would be limited to experimentally obtaining quantity values)

inɒzɘmɒЯ.A.M

Not bad not bad.

Bad.

quantity-calculus “set of mathematical rules and operations applied to quantities”

8:09 PM

@inɒzɘmɒЯ.A.M is there a meta post about what to do for this TRE?

inɒzɘmɒЯ.A.M

Q: The Great Retagging Event - Episode 1: The one-taggers

The first TRE event is done. Thanks for your attention folks! Here are the stats. When should the next one be? That, is the question. What good is in working so much on cleaning tags if they're not applied to questions? I thought, we should do something extraordinary. Oh no The Retagging Ev...

discussion featured tags retagging chat-event

It's all there.

I will help out before the TRE since I am not available at that time

inɒzɘmɒЯ.A.M

At what times are you available?

Now! And like five hours from now

Then I am available on Saturday UTC

inɒzɘmɒЯ.A.M

@Tan you can always go and retag stuff periodically.

But if you like, I'm ready to improve any edits you do, for fun and teaching's sake. :)

(Unless you know our tags well)

Which no one does, except @Mart.

8:15 PM

So I just follow the instructions in the meta post?

@inɒzɘmɒЯ.A.M

inɒzɘmɒЯ.A.M

@TanMath yES.

I mean yes.

OK

I'll try to start now...

inɒzɘmɒЯ.A.M

Good luck!

Good evening @inɒzɘmɒЯ.A.M o/

inɒzɘmɒЯ.A.M

\o

@Jan @Jan I'm answering you meta post.

@J.M.isback. Welcome to the Table!

8:27 PM

@inɒzɘmɒЯ.A.M tha~nks =D

@inɒzɘmɒЯ.A.M and hello to you too!

@Wild Flag! NAA! (No, I gave +1, but seriously xD More of an attempt at commenting on the question rather than answering ;) )

Hi @J.M.isback.

Where are you back from? @J.M.isback.

@Jan Long story short, I just came back from an SE hiatus.

Ah. Never been to hiatus. How is it there? Do they have nice weather? Snow maybe? =D Or is it a sizzle-in-the-sun type destination? D=

@Jan Not as fun as it sounds, I'm afraid. :)

8:32 PM

@J.M.isback. That's okay. I'm not being as serious as I might sound ;)

I mean, I'm in the condition 'it's half past ten and your compound is in the rotavap, you need to take an NMR of it and the last tram will leave in an hour' ^^'

@Jan what's the solvent?

Isohexanes : ethyl acetate 4:1

Yep, that'll take its sweet time to do, if it's somewhat saturated.

and I presume you'll be dissolving your compound in something deuterated, then

Saturated?

CDCl3 for the NMR, yup.

@Jan If it's taking long, either your bath is not that warm, or you have a lot of stuff dissolved

@Jan mmm, chloroform

8:39 PM

Oh, it's not taking long xD

In fact, I'm already going to zero pressure.

@Jan Oh. The way you put it, I thought you were waiting on the rotavap. :)

A vacuum oughta do it, yes.

I was waiting on it, but it silently finished while I was chatting here xD

@J.M.isback. There ain't nothing better for NMR =D

@Jan Well, back when carbon tet wasn't so restricted, that was the king.

that, or heavy water

Now, people are spoiled on deuterated solvents. ;)

I would prefer chloroform to both, because it has a 1H and a 13C signal … facilitates things greatly.

But then again, water with a drop of methanol works just as well, is only more trouble … still prefer CD3OD to D2O/MeOH xD

What is the best method to form a complex

8:54 PM

@Nadine Dissolve a transition metal in water. Boom, aqua-complex.

inɒzɘmɒЯ.A.M

Hullo @Nadine! Welcome to The Table!

Ok Sir

please , can you tell me how I can do the scavenging of selenium from phenylselenenyl chloride ?

I have no clue what you mean, sorry .__.'

no problem

the capture of selenium from phenylselenenyl chloride

inɒzɘmɒЯ.A.M

@Nadine Scavenging? O.o

9:05 PM

for example the scavenging of transition metal using modified silica in synthesis reactions

if the transition metal used as a catalyst

@Nadine 'Scavenging' is a term I associate with radicals …

Anyways, I'm off. See ya @inɒzɘmɒЯ.A.M @J.M.isback. o/

inɒzɘmɒЯ.A.M

@Jan \o

you are right Jan

can you give me an example please

9:51 PM

@inɒzɘmɒЯ.A.M I hoped I helped I will come back later to help

inɒzɘmɒЯ.A.M

@TanMath No problem!

@Jan some people includes IUPAC — Loong 1 min ago

@Loong you're a fun spoiler. (ノಠ益ಠ)ノ彡┻━┻

And a big one at that.

@inɒzɘmɒЯ.A.M sorry

inɒzɘmɒЯ.A.M

@Loong No no, I'm just messing. :) You could and edit the example, but that was never the point I was making in the answer. :/

@inɒzɘmɒЯ.A.M I know.

1 hour later…

11:10 PM

Anyone wanna tackle this

blog.chembark.com/2007/03/10/…

@Dissenter So much butthurt.

inɒzɘmɒЯ.A.M

@Dissenter Has a point, took it waaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaay too far.

@Dissenter I like this comment:

> I judge people by the units they use. Mr. Evans used kcal, so he lost

inɒzɘmɒЯ.A.M

11:27 PM

@Loong Of course you do. :D

So is he right or wrong

I don't think this issue was ever solved the last time I posted about it on SE

inɒzɘmɒЯ.A.M

I guess a bent shape is a bent shape, he's wrong @Dis.

I'm also like him, but to a way lesser extent.

Wait is this a famous chemist?

inɒzɘmɒЯ.A.M

> Hear everything, believe only the most sensible.

@Dissenter I wouldn't know.

He's saying

> Don't hear anything that isn't with a capital "I".

Lmao

Oh well

I have just accepted that in undergrad chemistry we often come to the right answer for the wrong reasons

inɒzɘmɒЯ.A.M

11:38 PM

So you see, going absolute never works well with nature.

At least we can still get to the right answer sometimes!

inɒzɘmɒЯ.A.M

@Dissenter Yes, and that ≠ nothing.

If I believe that the sun rises each day because of magnetism, is that really knowledge?

As opposed to believing that the sun rises each day because of the laws of planetary motion?

inɒzɘmɒЯ.A.M

Doesn't sun rise because someone's running on a treadmill and spinning Earth? :P

;)
