MCQ
Oxygen shows oxidation state of $-1$ in the compound :
- A$\mathrm{NO}_2$
- B$\mathrm{MnO}_2$
- C$\mathrm{PbO}_2$
- ✓$\mathrm{Na}_2 \mathrm{O}_2$
✓
Answer
Correct option: D.
$\mathrm{Na}_2 \mathrm{O}_2$
$\mathrm{Na}^2 \mathrm{O}^2$:
$2 + 2x = 0$
$\Rightarrow 2x = −2$
$\Rightarrow x = −1.$
$2 + 2x = 0$
$\Rightarrow 2x = −2$
$\Rightarrow x = −1.$
