Question

Quizplus · Accepted Answer

The reactive intermediate formed in the elimination-addition mechanism of nucleophilic aromatic substitution is benzyne. This intermediate is formed by heating an aryl halide in the presence of a strong base, which abstracts a proton to form a highly reactive arene intermediate. This intermediate then eliminates a leaving group to form the benzyne, which can then react with a nucleophile to form the final product.
