Organic Chem

[rockaction]

I have to be able to get the 60th percentile on the ACS exams. So, resonance, a lot of mechanisms, spectra without a chart to a degree, hybridization, stability or resonance forms, sigma/pi bonds (which is apparently also used to determine if something is aromatic...?), functional groups, etc, etc, etc. But I don't need to make the lab grades again, I have enough lab classes to show that I know my way around in lab.

The ACS exam will likely be way easier than your regular exams. Take heart in that! Most of my friends spent minimal effort studying for the final after doing well in the class got at least 60th percentile on the ACS exam. Be sure to get the official practice book, that thing is a life-saver.

Huckel's rule.

I found labs to be very useful, I learnt more organic chem theory doing 1 year of research in my MSc than I did in my whole undergrad.

Not to hijack your thread OP, but i have a question to ask relevant to σ bonds.

Take BeF2. Beryllium makes two sigma bonds with the two fluorides. My question is...
Why if Berylium has two electrons in its outer shell, does it not make ionic bonds, and it makes covalent ones?

 

[metherion]

Because, IIRC, hydrogen might just not be electronegative ENOUGH to make it a fully ionic bond.

Also, now I'm on to memorizing TWENTY TWO function groups. YAY.

alkanes
alkenes
alkynes
allenes
carbonyls
carboxylic acid
alcohols
ketones
esters
ethers
amines
amides
sulfides
sulfones
and a double handful of others that I'll need to look up. And memorize for tuesday. yay.

I loved organic chemistry when I did my A levels. Happy times.

Should of been a chemist and not a physicist.

Wish you all the best. Never found it easy and there was so much to remember.

keep on solving chemical reactions, and chemical problems and after a while you wont even think about what goes where and why...your hand will remember the reaction mechanism on its own
helps if you have a very good teacher though
