Vedclass · Answer

(C) The stability of carbocations is determined by the electronic effects of the substituents attached to the benzene ring. $(a)$ The tert-butyl group shows a $+I$ effect,which stabilizes the carbocation. $(b)$ The $-NO_2$ group shows a $-M$ effect,which strongly destabilizes the carbocation. $(c)$ The $-O-CO-CH_3$ group shows a $+M$ effect (due to the lone pair on oxygen),which significantly stabilizes the carbocation. $(d)$ The $-CH_3$ group shows a $+H$ (hyperconjugation) effect,which stabilizes the carbocation. Comparing the effects: $+M > +H > +I > -M$. Therefore,the order of stability is $c > d > a > b$.
