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.
