Vedclass · Answer

(C) Tautomerism is a special type of functional isomerism in which a compound exists in two or more interconvertible forms that differ in the relative position of at least one atomic nucleus,generally a hydrogen atom.For a carbonyl compound to exhibit tautomerism,it must possess at least one $\alpha$-hydrogen atom.$2-$Pentanone $(CH_3COCH_2CH_2CH_3)$ contains $\alpha$-hydrogen atoms on the carbon adjacent to the carbonyl group,and therefore it exhibits keto-enol tautomerism.
