Vedclass · Answer

(A) The reaction of benzene with succinic anhydride in the presence of $AlCl_3$ is a Friedel-Crafts acylation reaction. This reaction yields $4-$oxo$-4-$phenylbutanoic acid as product $A$ $(Ph-CO-CH_2-CH_2-COOH)$. The subsequent reaction with $Zn-Hg/HCl$ is a Clemmensen reduction,which reduces the carbonyl group $(C=O)$ to a methylene group $(-CH_2-)$. Therefore,the product $B$ is $4-$phenylbutanoic acid $(Ph-CH_2-CH_2-CH_2-COOH)$.

The structures of $A$ and $B$ formed in the following reaction are : $[Ph = -C_6H_5]$
