Which of the following could successfully undergo a Friedel-Crafts alkylation? Assume an appropriate catalyst.

Question

Quizplus · Accepted Answer

2-chlorobutane can successfully undergo Friedel-Crafts alkylation because it is an alkyl halide, and alkyl halides are commonly used in this reaction. Chlorobenzene (A) cannot undergo the reaction because it is already substituted and cannot be further modified. 2-chloroethene (B) is not a suitable substrate because it is a vinyl halide and can undergo polymerization instead of alkylation. 2-chloropropane (C) cannot undergo the reaction because it is a secondary alkyl halide, which can undergo rearrangement during the reaction.
