For this reaction, we have a tertiary alkyl halide, and we know that a tertiary alkyl halide will form a tertiary carbocation, which is a stable carbocation, and therefore an SN1 reaction is possible. mystic runes ring of powerWebMechanism: In the first step, the leaving group comes off to form a planar carbocation. In the second step, a β proton is removed by the base to give the alkene. Because of this two-step mechanism, E1 reactions do not require an anti periplanar geometry. The first step is slower and therefore determines the rate: it is the rate-determining step. mystic saint patricks day paradeWebAustin Community College District Start Here.
