Vedclass · Answer

(B) The reaction of a Grignard reagent $(C_6H_5MgBr)$ with carbon dioxide $(CO_2)$ followed by acid hydrolysis $(H_3O^+)$ is a standard method for the preparation of carboxylic acids.Step $1$: The nucleophilic phenyl group $(C_6H_5^-)$ from the Grignard reagent attacks the electrophilic carbon atom of $CO_2$ to form a magnesium carboxylate intermediate $(C_6H_5COOMgBr)$.Step $2$: Subsequent acid hydrolysis $(H_3O^+)$ converts the magnesium carboxylate into benzoic acid $(C_6H_5COOH)$.
