Determining SN1, SN2, E1, and E2 Reactions: Crash Course Organic Chemistry
Organic chemistry isn’t that different from an adventure game, with substrates as characters, nucleophiles as magic potions, and reaction conditions as different magical kingdoms. In this episode of Crash Course Organic Chemistry, we’ll...
Professor Dave Explains
Practice Problem: Drawing Substitution and Elimination Products (SN1/SN2/E1/E2)
I know you guys are dying for more practice choosing between SN1/SN2/E1/E2 mechanisms, so hopefully this one helps a little. Make sure to look at all the factors we talked about in my tutorial on this topic!
Professor Dave Explains
Choosing Between SN1/SN2/E1/E2 Mechanisms
When looking at a substrate and a base/nucleophile, how do we know which one of the basic mechanisms will occur? Let's get some tips in here!

Amine in Sn2 Part 2
An advanced chemistry class will understand Sal's reaction and see his logic in explaining the equilibrium. The levels of electronegativity and likelihood of a nucleophilic attack are balanced and presented in the equation. This is an...

Sn1 and Sn2 Epoxide Opening Discussion
After a helpful recap of the conditions that would suggest either Sn1, Sn2, or E1 reactions, this lecture provides exceptions to the usual rules.
