Sal presents certain mixtures of solvents and ions and runs through the factors that determine which reactions might occur in those contexts. This is an excellent review of not only the specifics of each reaction but also the real-life...

Sal looks at the same situation as in the previous video, but changes the base, or nucleophile. After changing to a more bulky molecule, Sal explains why the nucleophilic behavior is not as strong.

Building on the previous video, Sal further explains different situations and the reactions that would occur in each.

Reviews SN1 and SN2 reactions and compares how they are affected by different solvents.
