Vedclass · Answer

(D) The stability of a carbanion is increased by electron-withdrawing groups $(EWG)$ and decreased by electron-donating groups $(EDG)$ attached to the carbon bearing the negative charge.$1.$ Option $A$ is an alkyl carbanion with a phenyl group further away,providing minimal stabilization.$2.$ Option $B$ is a benzyl carbanion,stabilized by resonance with the phenyl ring.$3.$ Option $C$ has a $-OCH_3$ group,which is an electron-donating group (via $+M$ effect),thus destabilizing the carbanion.$4.$ Option $D$ has a $-NO_2$ group,which is a strong electron-withdrawing group (via $-M$ and $-I$ effects). It effectively disperses the negative charge through resonance,making it the most stable carbanion among the given options.
