MCQ
The correct stability order of the given canonical structures is
- A$I > II > III$
- ✓$III > I > II$
- C$I > III > II$
- D$II > III > I$
✓
Answer
Correct option: B.
$III > I > II$
b
$(b)$ Structure $III$ & $I$ has complete octet for all atoms but $III$ is more stable than $I$ because $N^{\oplus} > O^{\oplus}$ is the stability order.
