Mechanisms of Alpha Substitution Reactions | 21.2 Organic Chemistry

Chad covers the two general mechanisms of Alpha Substitution reactions in this lesson: the base-catalyzed mechanism (or base-promoted) and the acid-catalyzed mechanism including all arrow-pushing. The base-promoted mechanism involves an enolate ion as the nucleophile, while the acid-catalyzed mechanism involves an enol as the nucleophile.
