Vedclass · Answer

(B) Keto-enol tautomerism requires the presence of at least one $\alpha$-hydrogen atom adjacent to the carbonyl group $(C=O)$.In $C_6H_5COCH_3$ (acetophenone),the $CH_3$ group is attached to the carbonyl carbon,which provides three $\alpha$-hydrogen atoms.These $\alpha$-hydrogens are acidic and can be removed to form an enolate,leading to tautomerism.In $C_6H_5CHO$,$C_6H_5COC_6H_5$,and $C_6H_5COC(CH_3)_2C_6H_5$,there are no $\alpha$-hydrogen atoms available adjacent to the carbonyl group,so they do not exhibit keto-enol tautomerism.
