E2 Reactions. E2 = elimination, bimolecular Reaction is concerted (one step) Rate = k[substrate][base] (a second order process) E2 can occur with S N 2. Occurs by abstraction of H + from a C adjacent to the C with the LG. Products follow Zaitsev’s Rule.By satya

Substitution Reactions – S N 1. Recall that the following reaction does not proceed via an S N 2 mechanism. The electrophilic carbon atom is too sterically crowded for the nucleophile to attack it. For this type of substrate, the reaction proceeds by a different mechanism, an S N 1 mechanism. .By velika
