Vedclass · Answer

(C) The stability of a carbocation is determined by factors such as resonance,hyperconjugation,and inductive effects. $A$: Cyclohexyl cation is a secondary carbocation with no resonance stabilization. $B$: Cyclohex$-2-$en$-1-$yl cation is an allylic carbocation,which is stabilized by resonance with the adjacent double bond. $C$: $1-$methyl$-2-$phenylcyclohex$-2-$en$-1-$yl cation is a tertiary allylic carbocation. It is stabilized by resonance with the adjacent double bond and the phenyl group,as well as by the inductive effect of the methyl group. This extensive delocalization of the positive charge makes it the most stable among the given options. $D$: ($3$-phenylcyclohexyl)methyl cation is a primary carbocation,which is generally the least stable. Therefore,the most stable carbocation is the one in option $C$.
