WebA leaving group , LG, is an atom (or a group of atoms) that is displaced as stable species taking with it the bonding electrons. Typically the leaving group is an anion ( e.g. Cl -) or a neutral molecule ( e.g. H 2 O). The better the leaving group, the more likely it is to depart. WebE2 mechanism. E2 indicates an elimination, bimolecular reaction, where rate = k [ B ] [ R - LG ]. This pathway is a concerted process with the following characteristics: Simultaneous removal of the proton, H +, by the base, loss of the leaving group, LG, and formation of the π-bond. Let's look at how the various components of the reaction ... shane fordyceThe requirement for a good leaving group is relaxed in conjugate base elimination reactions. These reactions include loss of a leaving group in the β position of an enolate as well as the regeneration of a carbonyl group from the tetrahedral intermediate in nucleophilic acyl substitution.
