Vedclass · Answer

(B) The given compound $Ph-CH=NO_2H$ is an aci-nitro compound. Nitro-aci-nitro tautomerism is a type of tautomerism where a nitro compound $(R-CH_2-NO_2)$ exists in equilibrium with its aci-form $(R-CH=NO_2H)$. In this case,the aci-nitro form $Ph-CH=NO_2H$ tautomerizes to the stable nitro form $Ph-CH_2-NO_2$. Therefore,the isomer $(x)$ is $Ph-CH_2-NO_2$.
