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