Vedclass · Answer

(B) The stability of a carbocation is increased by electron-donating groups $(EDG)$ and decreased by electron-withdrawing groups $(EWG)$.$1$. The $-NO_2$ group is a strong electron-withdrawing group ($-I$ and $-M$ effect),which destabilizes the carbocation.$2$. The $-OCH_3$ group is an electron-donating group ($+M$ effect),which significantly stabilizes the carbocation by donating electron density through resonance.$3$. The $-Cl$ group is electron-withdrawing ($-I$ effect) but also has a weak $+M$ effect; overall,it is less destabilizing than $-NO_2$ but less stabilizing than $-OCH_3$.$4$. The unsubstituted benzyl carbocation $(C_6H_5-CH_2^+)$ serves as the reference.Therefore,the species with the $-OCH_3$ group is the most stable.
