Question

Quizplus · Accepted Answer

The elimination-addition mechanism of nucleophilic aromatic substitution involves the formation of a reactive intermediate called benzyne. This is formed by elimination of a leaving group from an aryl halide to generate a strained, triple-bonded intermediate. The benzyne can then be attacked by a nucleophile, leading to substitution at the aromatic ring.
