Vedclass · Answer

(C) To determine the stability of carbocations,we consider the electronic effects (resonance,hyperconjugation,and inductive effect).$1$. $CH_3-O-CH_2^+$: The oxygen atom has lone pairs of electrons that can participate in resonance with the empty $p$-orbital of the carbocation $(CH_3-O^+=CH_2)$. This $+M$ (mesomeric) effect provides significant stability.$2$. $(CH_3)_3C^+$: This is a tertiary carbocation stabilized by hyperconjugation from $9$ $\alpha$-hydrogens.$3$. $CH_2=CH-CH_2^+$: This is an allyl carbocation,stabilized by resonance.$4$. Phenyl carbocation $(C_6H_5^+)$: The positive charge is on an $sp$-hybridized carbon atom in the ring,which is highly unstable due to the high $s$-character and lack of resonance stabilization for the positive charge.Comparing these,the resonance stabilization provided by the lone pair on the oxygen atom in $CH_3-O-CH_2^+$ is the most effective in stabilizing the positive charge. Therefore,$CH_3-O-CH_2^+$ is the most stable.
