Vedclass · Answer

(C) The stability of carbocations is determined by resonance,hyperconjugation,and inductive effects.$I$ and $IV$ are stabilized by resonance due to the lone pair on the oxygen atom adjacent to the carbocation center. Between $I$ and $IV$,$I$ is more stable because the resonance structure involves a more substituted oxonium ion.$III$ and $II$ are stabilized by hyperconjugation. $III$ is a secondary carbocation with $5$ alpha-hydrogens,while $II$ is a secondary carbocation with $4$ alpha-hydrogens. Therefore,$III > II$.The overall stability order is $I > IV > III > II$.

The correct stability order for the following carbocations is:
