MCQ
Relative stability of the contributing structures is :
- A(I) > (III) > (II)
- ✓(I) > (III) > (II)
- C
- D(III) > (II) > (I)
✓
Answer
Correct option: B.
(I) > (III) > (II)
(B)
(1) 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., $C ^{\oplus}$ is more stable than $O ^{\oplus}$
$\therefore \quad$ Order is $I > II > III$
