Vedclass · Answer

(A) The stability order is determined as follows:$IV$ is the most stable because the lone pair on the oxygen atom participates in back bonding with the empty $p$-orbital of the carbocation,providing resonance stabilization.$I$ is a secondary $(2^o)$ carbocation,which is more stable than a primary $(1^o)$ carbocation.$III$ is a primary $(1^o)$ carbocation.$II$ is the least stable because the positive charge is located at the bridgehead position of a bicyclic system,which is highly unstable due to significant angle strain (Bredt's rule).Therefore,the correct order is $IV > I > III > II$.

Find the correct stability order for the following carbocations:
