AIIMS 2018 Chemistry Friedel-Crafts Reactions MCQ Question

Friedel-Crafts alkylation involves the introduction of an alkyl group into an aromatic ring using an alkyl halide and a Lewis acid catalyst, typically resulting in the formation of a more stable carbocation intermediate. In contrast, free radical substitution reactions involve the generation of free radicals, which can lead to the substitution of hydrogen atoms in alkanes or aromatic compounds, but do not typically result in the formation of stable carbocations as seen in Friedel-Crafts reactions. Therefore, option B correctly identifies the reaction type as Friedel-Crafts alkylation, while the other options do not pertain to this specific mechanism or are not applicable to the context of the question.
