Vedclass · Answer

(B) The stability of carbocations is determined by the electronic effects of the substituents attached to the positively charged carbon atom.$1$. In $(Y)$,the $-OCH_3$ group exerts a strong $+M$ (mesomeric) effect,which significantly stabilizes the carbocation by donating electron density through resonance.$2$. In $(X)$,the two $-CH_3$ groups provide stability through $+I$ (inductive) effect and hyperconjugation.$3$. In $(Z)$,the $-COCH_3$ group is an electron-withdrawing group due to its $-I$ and $-M$ effects,which destabilizes the carbocation.Therefore,the order of stability is $Y > X > Z$.

What is the order of stability of the following carbocations?
$(X). CH_3 - \overset{\oplus}{C}H - CH_3$
$(Y). CH_3 - \overset{\oplus}{C}H - OCH_3$
$(Z). CH_3 - \overset{\oplus}{C}H - COCH_3$
