Vedclass · Answer

(D) The stability of a carbocation is increased by the presence of electron-donating groups that can stabilize the positive charge through resonance.In the given options,the methoxy group $(-OCH_3)$ acts as a strong electron-donating group due to the $+M$ (mesomeric) effect.Among the options,the carbocation $CH_3O-CH=CH-CH=CH^+$ is the most stable because the positive charge is delocalized over a larger conjugated system,and the $+M$ effect of the $-OCH_3$ group is effectively transmitted through the extended conjugation to stabilize the carbocation.

Which of the following carbocations is most stable?
