Vedclass · Answer

(C) Tautomerism,specifically keto-enol tautomerism,requires the presence of at least one $\alpha$-hydrogen atom on the carbon atom adjacent to the carbonyl group.$1.$ In acetaldehyde $(CH_3-C(=O)-H)$,the $\alpha$-carbon is attached to three $\alpha$-hydrogen atoms,thus it exhibits tautomerism.$2.$ In formaldehyde $(H-C(=O)-H)$,there is no $\alpha$-carbon atom present.$3.$ In pivalaldehyde $(CH_3-C(CH_3)_2-C(=O)-H)$,the $\alpha$-carbon is bonded to three methyl groups and possesses no $\alpha$-hydrogen atoms.Therefore,only option $(C)$ shows tautomerism.

Which of the following compounds exhibits tautomerism?
