WebThe elimination reaction consists of three fundamental events, and they are; Proton removal. Formation of C-C pi bond. Removal of the leaving group. Depending on the reaction kinetics, elimination reactions can occur mostly by two mechanisms namely E1 or E2 where E is referred to as elimination and the number represents the molecularity. WebA few reasons: 1. The C-Br bond is relatively weak (<300kJ/mol) compared to other C-X bonds. The C-I bond is even weaker. The kinetic energy supplied by room temperature is enough to get the Br to spontaneously dissociate. 2. Br is a large atom, with lots of protons and electrons. Leaving groups need to accept a lone pair of electrons when they ...

It is similar to a unimolecular nucleophilic substitution reaction (S N 1) in various ways. One being the formation of a carbocation intermediate. Also, the only rate determining (slow) step is the dissociation of …
