thanks to the student for allowing this to be posted and obviously thanks to the prof!

Thank you so much for posting these videos. You are an excellent prof and very good at dispelling the black magic associated with orgo. I got my degree in chemistry, and graduated with an okay gpa, I guarantee if I had watched these videos, I would have graduated with a lot higher gpa. Keep up the good work and please keep posting more videos. You are helping out so many people!

Fully thought that was AlH3 ..

Where is the start of this.. even the first video starts "half" way. I was wondering where the introduction video to Sn1/Sn2 reactions is?

[expensivepink001]

i understand why we have to deprotanate but doesnt that mean that Sn2 then has 2 steps and not one? because the first step is the LG leaving and nu atttaching at the same time and then the next step would be the deprotanation ??

LOL....figures.... right after typing my first comment, I unpause the video and the tutor says..."of course there's usually more than one way to do things; if I told you the solvent, you could've had a solvent molecule come in and grab the hydrogen." He's worth his salt after all. I rescind my previous comment but will leave it posted since it IS accurate.

A real organic chemist would have known what a shitty base Iodide is, and would have brought another ammonia molecule in to abstract the proton off nitrogen, leaving Ammonium and Iodide ions. This guy oughta know that HI wont exist in the presence of NH3. The acid-base rxn between them has an equilibrium constant of approx 13, which favors formation of Ammonium Iodide.

@GracusDO you is welcome bia!

he looks like the allan from 2 n half men

You have over 50,000 views from kids all across the world watching your videos to improve on organic chemistry. This is real teaching. Thank you sir.

Mr. Tutor really knows his stuff.
