Vedclass · Answer

(B) The stability of carbocations is determined by factors like resonance,hyperconjugation,and inductive effects.$1$. $CH_3-\stackrel{\oplus}{C}H_2$ (Ethyl carbocation) is stabilized by hyperconjugation.$2$. $CH_2=\stackrel{\oplus}{C}H$ (Vinyl carbocation) has the positive charge on an $sp$-hybridized carbon atom. Since $sp$ carbons are more electronegative,they hold the positive charge very poorly,making it highly unstable.$3$. $CH_2=CH-CH_2^{\oplus}$ (Allyl carbocation) is stabilized by resonance.$4$. $C_6H_5-\stackrel{\oplus}{C}H_2$ (Benzyl carbocation) is stabilized by resonance with the benzene ring.Therefore,the vinyl carbocation is the least stable.
