Vedclass · Accepted Answer

$CH_3-NO_2$

Vedclass · Answer

(B) Tautomerism requires the presence of at least one $\alpha$-hydrogen atom adjacent to a functional group like a carbonyl $(-C=O)$ or nitro $(-NO_2)$ group.$A$. $CH_3-C(CH_3)_2-CHCl$: This molecule lacks a carbonyl or nitro group,so it does not exhibit tautomerism.$B$. $CH_3-NO_2$: This molecule has $\alpha$-hydrogen atoms on the carbon attached to the $-NO_2$ group. It exhibits nitro-aci tautomerism: $CH_3-NO_2 \rightleftharpoons CH_2=N(O)OH$.$C$. The structure shown is $4,4$-dimethylcyclohexa-$2,5$-dienone. The carbon atoms adjacent to the carbonyl group (the $\alpha$-carbons) are fully substituted by methyl groups and the ring structure,meaning there are no $\alpha$-hydrogen atoms available for tautomerization.Therefore,only $B$ exhibits tautomerism.

In which of the following molecules is tautomerism possible?
