Vedclass · Answer

(B) The correct stability order of the given carbocations is $II > I > III$. In structure $II$,the presence of the electron-releasing $-NMe_2$ group significantly stabilizes the carbocation through the $+M$ effect. In structure $I$,the carbocation is stabilized by resonance with the benzene ring. In structure $III$,due to $SIR$ (Steric Inhibition of Resonance),the $-C(Me)_2^+$ group is forced out of the plane of the benzene ring by the two ortho-methyl groups. This loss of conjugation significantly decreases its stability compared to $I$ and $II$.

The stability of the following carbocations follows the order:
