Vedclass · Answer

(C) The stability of carbocations is determined by factors such as resonance,hyperconjugation,and inductive effects. $A$: Cyclohexyl carbocation is a secondary $(2^{\circ})$ alkyl carbocation with no resonance stabilization. $B$: Cyclohex$-2-$en$-1-$yl carbocation is an allylic carbocation,which is stabilized by resonance with the adjacent double bond. $C$: Cyclohexa$-2,4-$dien$-1-$yl carbocation is a conjugated dienyl carbocation. It has more resonance structures compared to the allylic carbocation in $B$,making it more stable due to extended delocalization of the positive charge. $D$: Phenyl carbocation is an $sp$-hybridized carbocation where the positive charge is on the ring,which is highly unstable due to the high electronegativity of the $sp$-hybridized carbon. Comparing these,the resonance stabilization in the conjugated system of $C$ makes it the most stable among the given options.
