Vedclass · Answer

(D) The stability of carbocations is determined by electronic effects:$1$. In $II$ $(^+CH_2-OCH_3)$, the oxygen atom has lone pairs that can donate electron density through resonance ($+M$ effect), completing the octet of the carbon atom, making it the most stable.$2$. In $III$ $(^+CH_2-CH_3)$, the ethyl group provides stability through hyperconjugation and the inductive effect ($+I$ effect) of the methyl group.$3$. In $I$ $(^+CH_2-COCH_3)$, the carbonyl group $(-C=O)$ is a strong electron-withdrawing group ($-I$ and $-M$ effect), which destabilizes the positive charge, making it the least stable.Therefore, the order of stability is $I < III < II$.

For the following carbocations, the correct order of stability is:
$I: ^+CH_2-COCH_3$
$II: ^+CH_2-OCH_3$
$III: ^+CH_2-CH_3$
