A)  Acetyl benzoic acid

B)  Anisol

C)  Acetophenone

D)  Chlorobenzene

Correct Answer: C

Solution :

                 Key Idea Friedel-Craft reaction When benzene is heated with alkyl halide or acyl halide in the presence of anhydrous \[AlC{{l}_{3}}\] then hydrogen atom of benzene is replaced by alkyl or acyl group respectively.                 When benzene is heated with acetyl chloride in presence of anhydrous \[AlC{{l}_{3}}\], acetophenone is obtained. In this reaction electrophilic substitution takes place.
