Elimination (E1 & E2)

7 reactions in this topic, each with the reagents, the mechanism and the structure of the product.

When treated with phosphorus oxychloride (POCl3) alcohols are converted to alkenes via an elimination reaction.

Addition of acid to alcohols can result in elimination to form the corresponding alkene along with a molecule of water. Because wa

With E1 and E2 mechanisms we have already met, but let’s compare them now. Both are elimination reactions. When alkyl halides reac

When unstable carbocations are formed under conditions typical for E1 reactions, hydride shift can occur.

Alkyl halides that can readily form carbocations will undergo elimination to form alkenes.

Addition of a strong base to an alkyl halide results in elimination to form an alkene.

Tetra-alkyl ammonium salts undergo elimination to form the least substituted alkene. This is called the Hofmann elimination.
