Vedclass · Answer

(A) The reaction between benzene and acetic anhydride in the presence of anhydrous $AlCl_3$ is a Friedel-Crafts acylation reaction.Step $I$: The Lewis acid $AlCl_3$ coordinates with the oxygen atom of acetic anhydride,leading to the formation of an acylium ion $(CH_3-C^+=O)$ and an acetate-aluminum complex.Step $II$: The electrophilic acylium ion attacks the benzene ring via Electrophilic Aromatic Substitution $(ESR)$ to form acetophenone $(C_6H_5COCH_3)$.
