Vedclass · Answer

(D) Tautomerism is exhibited by compounds that have at least one $\alpha$-hydrogen atom attached to a carbon atom adjacent to a functional group like nitro $(-NO_2)$ or nitroso $(-NO)$.In option $D$,the compound $R-CH_2NO_2$ contains two $\alpha$-hydrogen atoms on the carbon atom attached to the $-NO_2$ group.These $\alpha$-hydrogens are acidic and can migrate to the oxygen atom of the nitro group to form an aci-nitro form,thus exhibiting tautomerism.Options $A$,$B$,and $C$ do not possess any $\alpha$-hydrogen atoms,so they cannot show tautomerism.
