Vedclass · Answer

(A) The stability of carbocations is determined by electronic effects:$1$. Mesomeric effect $(+M)$: Groups like $-NH-$ and $-OCH_3$ stabilize the carbocation by donating a lone pair through resonance. The $+M$ effect of Nitrogen is stronger than that of Oxygen because Nitrogen is less electronegative,making $(iii)$ more stable than $(i)$.$2$. Hyperconjugation and Inductive effect $(+I)$: Alkyl groups stabilize carbocations. $A$ tertiary carbocation $(ii)$ is more stable than a primary carbocation $(iv)$.Comparing these,the overall stability order is $(iii) > (i) > (ii) > (iv)$.

Stability order of the following carbocations:
$(i) CH_3 - C^{+}(OCH_3) - CH_3$
$(ii) CH_3 - C^{+}(CH_3) - CH_3$
$(iii) CH_3 - NH - C^{+}H_2$
$(iv) CH_3 - C^{+}H_2$
