Nitromethane = MENO2 OR CH3NO2 ?????????
|
|
|
Swig is really confused tonight.
He UTFSE and found out that MeNo2 is refered as nitromethane some places (Reductive amination of MDP2p with Al/Hg + Nitromethane for instance) and CH3NO2 some other place.
SWIG also found reagent grade Nitromethane 95% somewhere, the formula given is CH3NO2.
-Is this CH3NO2 nitromethane ok for the reductive amination ????
-Why 2 different formulas for the same coumpound ???
arghhhhhhhhhhhh :(

MeOH Methanol
|
|
|
Yeah you will find Methanol (CH3OH) as MeOH in some places too.
When swim started with chemistry he thought that this MeOH means Metal+ OH group. As described in some chemistry books for acid base reactions.

Gets even more fun than that....

PhMe = toluene PhH = benzene
HOAc = acetic acid Ac2O = acetic anhydride EtOAc = ethyl acetate
Bn = PhCH2 = C6H5CH2 = benzyl (a common protecting group)
BnCl = PhMeCl = C6H5CH2Cl = benzyl chloride
Pr = propyl (sometimes) iPr = isopropyl
Now it gets even more fun:
PhAc = acetophenone PhEtNH2 = C6H5.CH2.CH2.NH2 = phenethylamine (see where the name came from?)
You can probably imagine how these funny abbreviations make reading posts easier. Those H's get annoying after awhile.
So can you guess what:
MeCN is?
How about EtOH? (we drink it...) Or the oh-so-desired EtNO2?
What movie do they use Et2O in? (pick one) What was it used for?
When you have some BnCN aka PhCH2CN and EtOAc, and NaOEt, what can you make? If you have some HCOOH and MeNH2, then what?
Isn't this fun? And so much hipper than merely spelling out what you mean to say! Practice a bit and you'll be slinging chemspeak jargon like a pro in no time!
Hey, bees, any other fun abbreviations I forgot? We should make a hivespeak dictionary, and a companion "tweakspeak" volume, as well.
I've been chased by both cops and robbers. So what does that make me?
