Vedclass · Answer

(A) The stability of carbocations depends on factors like resonance,hyperconjugation,and the electronegativity of the carbon atom bearing the positive charge.$A$ (Benzyl carbocation) is the most stable due to resonance stabilization by the benzene ring.$C$ $(CH_3-CH_2^+)$ is a primary alkyl carbocation,which is stabilized by the inductive effect $(+I)$ of the methyl group.$B$ $(CH_2=CH^+)$ is a vinyl carbocation where the positive charge is on an $sp^2$ hybridized carbon,which is more electronegative than an $sp^3$ carbon.$D$ $(HC \equiv C^+)$ is an acetylenic carbocation where the positive charge is on an $sp$ hybridized carbon,which is the most electronegative among the three $(sp > sp^2 > sp^3)$.Since a positive charge is less stable on a more electronegative atom,the order of stability for $B, C,$ and $D$ is $C > B > D$.Combining these,the overall order of stability is $A > C > B > D$.

The correct order of stability of the given carbocations is:
