Vedclass · Accepted Answer

$II < I < IV < III$

Vedclass · Answer

(A) The stability order is $II $1$. Structure $III$ (methoxycyclohexyl cation) is the most stable due to the $+M$ effect of the oxygen atom,which donates electron density to the positively charged carbon.$2$. Structure $IV$ (ethylcyclohexyl cation) is more stable than $I$ (methylcyclohexyl cation) because the ethyl group provides more hyperconjugation and inductive stabilization than the methyl group.$3$. Structure $II$ is a bridgehead carbocation. According to Bredt's rule,bridgehead carbocations in small bicyclic systems are highly unstable because they cannot achieve the required $sp^2$ planar geometry due to severe ring strain.

Arrange the following carbocations in the correct order of stability:
