Vedclass · Answer

(A) The stability of the given carbocations is determined by resonance,aromaticity,and hybridization:$(i)$ Cyclopropenyl cation is aromatic ($2\pi$ electrons,Huckel's rule),making it highly stable.(ii) Benzyl carbocation $(C_6H_5CH_2^+)$ is stabilized by resonance with the benzene ring.(iii) Allyl carbocation $(CH_2=CH-CH_2^+)$ is stabilized by resonance with the double bond.(iv) Vinyl carbocation $(CH_2=CH^+)$ is highly unstable because the positive charge is on an $sp$-hybridized carbon atom,which is more electronegative.Comparing their stabilities:- $(i)$ is aromatic,so it is the most stable.- $(ii)$ is resonance-stabilized by a benzene ring,which is more stable than the simple allyl cation $(iii)$.- $(iii)$ is resonance-stabilized.- $(iv)$ is the least stable due to the $sp$-hybridized carbon.Thus,the correct order is $(i) > (ii) > (iii) > (iv)$.

The correct order of stability of the carbocations given below is:
