JEE Main 2024 — 9 April, Shift 1 — Question 65

Relative stability of the contributing structures is :

Option A:
(I) $>$ (III) $>$ (II)
Option B:
(I) $>$ (II) $>$ (III)
Correct
Option C:
(II) $>$ (I) $>$ (III)
Option D:
(III) $>$ (II) $>$ (I)

Answer: B

Step-by-step solution

Neutral structures are more stable than charged ones. Therefore I is more stable than II and III.

(2) +ve charge on less electronegative atom is more stable i.e., $\mathrm{C}^{\oplus}$ is more stable than $\mathrm{O}^{\oplus}$

$\therefore \quad$ Order is $\mathrm{I}>\mathrm{II}>\mathrm{III}$
