Alkyl halides may undergo elimination reactions with BrØnstead-Lowry bases in which the halide and an adjacent proton are lost to form a new π bond. Because of the loss of a proton and a halide anion the reactions are termed ‘dehydrohalogenation’. The two most common associated mechanisms are designated as either unimolecular (E1) or bimolecular (E2) elimination reactions based on reaction rate studies. E1 reactions proceed via a two-step mechanism that involves the cleavage of the leaving group (here the...

Please, make the answer clear
and reable.
BrEtOH a OEt Hace H2C Alkyl halides undergo nucleophilic substitution and elimination reactions. When the kinetics of the reaction are measured, if the rate of the reaction is found to be dependent only upon the concentration of the alkyl halide the reaction is first order. The substitution reaction is thus termed ction is termed E1. These reactions are unimolecular and occur in two steps. The first step is rate-limiting and involves the loss...
