^^Thats funny, I had the exact same experience with organic chemistry.
Not until I had a decent understanding of physics (I studied phyics as a junior and Organic as a Sophomore) was I able to really understand and appreciate quantum chemistry.
I would like to return to the subject now with greater understanding of the implications of the Bohr model in physics.

Pop Quiz HOTSHOTS!
One of the kids who works for me has asked about this:
https://webfiles.uci.edu/mkladney/ochem.PDF
I've got an idea of how it works, but I can't get the (correct) answer to save my life. Apparently it comes straight out of the book (which I don't have - i've given all the copies away to all the other kids who work for me). I won't be able to get a copy of the book for a few more days...
So, i turn to you bluelight!
Anyone?

it essentially makes an allylic carbanion (grinard analogue). but i can't get the same answer as what is posted...annoying. i think it is a typo.

new question!
which is more acidic cyclopropane or cyclopropene?

That looks like a variation on a Wittig reaction.

Whew! Too hard for me!
That cyclic diester of boric acid...that's some reagent that new to me. However, seeing as I took Orgo in 1978, that's not unusual.
My guess is that it's reacting with that allyl halide by adding to the double bond, leaving the bromine on there. Then, the product halide reacts with the triphenylphosphine derivative, makes a Wittig reagent, then that attacks some carbonyl moiety generated on one of those R groups attached to the boron...generated by some rearrangement that's beyond my knowledge.
It's one of those elegant jobbers that makes you say "of course" when somebody shows you the answer and draws all those little 'which electron goes where' arrows.

I'm finished with ochem, got a B in Ochem1 and an A in Ochem2. It wasn't as tough as I thought it would be. Genetics at my uni is way harder.

I got Cs on OChem I & 2, but I can tell you the secret is to keep up with the work, otherwise you're fucked.
