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...

Substitution Reactions - SN1 and SN2 Mechanisms - Crash Course Organic Chemistry
We’ve already learned a bit about substitution reactions in organic chemistry and the two different paths they can follow: SN1 and SN2. In order to better predict the products of a substitution reaction and understand how they work, we...

Ritter Reaction
It's the Ritter reaction! Named after its inventor, John Ritter. No, not the actor from Three's Company. A different guy. This is a great way to go from an alcohol or alkene to an amine. How does it work? What are chemists doing with...
