Vedclass · Answer

(B) . $CH_3-CH^{+}-OCH_3$ is the most stable due to the $+M$ effect of the oxygen atom,which donates electron density to the carbocation.$a$. $CH_3-CH^{+}-CH_3$ is a secondary carbocation stabilized by the $+I$ effect and hyperconjugation of two methyl groups.$c$. $CH_3-CH^{+}-COCH_3$ is the least stable because the carbonyl group $(-COCH_3)$ exerts a strong $-I$ and $-M$ effect,which destabilizes the positive charge.Therefore,the decreasing order of stability is $b > a > c$.

Arrange the following carbocations in the decreasing order of their stability:
$a$. $CH_3-CH^{+}-CH_3$
$b$. $CH_3-CH^{+}-OCH_3$
$c$. $CH_3-CH^{+}-COCH_3$
