$CH_3COCH_3$

Vedclass · Answer

(C) The correct answer is $(C)$.Acetone $(CH_3COCH_3)$ shows keto-enol tautomerism because it contains $\alpha$-hydrogen atoms adjacent to the carbonyl group.The keto form exists in equilibrium with its enol form:$CH_3COCH_3 \rightleftharpoons CH_3-C(OH)=CH_2$.$HCHO$ and $HCOOH$ do not have $\alpha$-carbons,and while $CH_3CN$ can show nitrile-ketenimine tautomerism,$CH_3COCH_3$ is the standard example for keto-enol tautomerism.

Which of the following compounds shows tautomerism?
