Which of the following halides cannot be used for Friedel-Crafts alkylation reaction?

Question

Quizplus · Accepted Answer

Friedel-Crafts alkylation reactions require a carbocation intermediate, which cannot be formed easily from substrates that are either too stable or too unstable. Bromobenzene (A) cannot undergo Friedel-Crafts alkylation because it is an aryl halide, and the sp2 hybridized carbon attached to the halogen does not form a carbocation easily. Vinyl chloride (B) also cannot undergo this reaction because it is a vinyl halide, and the sp2 hybridized carbon adjacent to the double bond also does not form a carbocation readily.
