What constitutes a non-bulky base and a bulky base? What is the difference? I understand that the bulky base is different because its larger, but exactly how much larger? What is the definition of bulky...more than one methyl group, greater molecular mass???
why didn't he write the iodine at the end with the negative charge since it was eliminated? i am just confused why would that be wrong?? anyways this helps A TON because my book is so confusing and my prof goes very fast. these reactions are not that difficult you just must memorize the patterns and the handout def helps! i will donate after my o chem class is over and hopefully pass!
@bungerman1000 i think that we were using the same base as before, but the subscript 3 was just forgotten. i am pretty sure he meant to write (CH3)3CO- (i am assuming that you are talking about the second reaction with the iodocyclohexane.)
I'm pretty good at ochem, but I've always had an issue with some things clicking.
THANK YOU! They have finally clicked. You, my friend, are what a teacher is: Someone who gives their time and energy to altruistically help aspiring pupils. You seriously need to have your videos put into the Teaching Company series.
@brothadave I presume it depends on which specific reaction as it might react with other substituents or with itself or the solvent used (if any) but for first year chem stuff I wouldn't have thought it matters too much if you disregard it. Anyone feel free to correct me though because I'm not the greatest chemist in the world
Thank you so much for these videos! I have a question though (for anyone), how did we know that the (CH3)CO- was acting as a base instead of a nu? I thought the reaction with the iodocyclohexane would have been a SN2 instead of E2. Sorry for the trouble and thank you in advance! :)
@AutumnTeaLeaves It is acting as a base because it is so big and bulky. A good nucleophile will never be big and bulky, but this makes a really good base.
I've heard nothing but horror stories about O.chem professors so when I got a good one I was nothing but thankful... then I found these videos and they still put her to shame!!! My prof is still a sweetheart though.. a cute little old lady with a Persian accent haha
God bless you!

why is this a bulky base? it only has 1 methyl group

@bungerman1000 never mind he answered my question later and forgot the 3.

@bungerman1000 it has 3 methyl group bonded to C

can we disregard where the I ends up and just assume it forms I2?

These videos are gems. I was wondering when he would get to the cyclic molecules and BAM! I love this.

NU in Boston, this guy's way better than my prof. I wish students could have their say on hiring professors.
