Vedclass · Answer

(C) Acetophenone $(C_6H_5COCH_3)$ undergoes standard electrophilic aromatic substitution reactions because the acetyl group is deactivating and meta-directing.Therefore,statement $III$ is incorrect.Acetophenone contains a methyl ketone group $(-COCH_3)$,so it gives a positive iodoform test with iodine and alkali.Therefore,statement $IV$ is incorrect.Statement $I$ is correct: Reduction of acetophenone with $Na/C_2H_5OH$ yields $1$-phenylethanol (methyl phenyl carbinol).Statement $II$ is correct: Oxidation of acetophenone with acidic $KMnO_4$ yields benzoic acid.Thus,statements $III$ and $IV$ are incorrect.
