Vedclass · Answer

(B) The given reaction is a Friedel-Crafts acylation of anisole $(C_6H_5OCH_3)$.Anisole reacts with acetyl chloride $(CH_3COCl)$ in the presence of anhydrous aluminum chloride $(AlCl_3)$ as a Lewis acid catalyst.This reaction introduces an acetyl group $(-COCH_3)$ at the ortho and para positions of the benzene ring.Since the methoxy group $(-OCH_3)$ is ortho/para directing,the para-isomer is formed as the major product due to less steric hindrance compared to the ortho-isomer.Therefore,the missing reagent is $CH_3COCl / AlCl_3$.

Identify the missing reagent in the following reaction: $C_6H_5OCH_3 + (?) \rightarrow \text{p-methoxyacetophenone (major)} + \text{o-methoxyacetophenone (minor)}$
