Elimination (Organic Chemistry)
What are the major elimination products A and B, which are obtained from the reaction of each of the following alkyl halides with hydroxide ion? Explain your answers in each case. Draw and discuss the most likely mechanism of these elimination reactions.
Homework Answers
The product of the reactions are given below.
In the case of reaction-l, a more substituted alkene product A is formed after the elimination of HBr. The proton will be abstracted from the carbon, which will lead to a more stable product. For reaction-Il less substituted product B will be formed as there is only one carbon next to the carbon attached to bromine which has hydrogen atoms to facilitate elimination reaction.

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...
