MCQ
Oxidation state of nitrogen is not an integer in :
  • A
    Hydroxyl amine $\left(\mathrm{NH}_2 \mathrm{OH}\right)$
  • B
    Ammonia $\left(\mathrm{NH}_3\right)$
  • C
    Hydrazine $\left(\mathrm{N}_2 \mathrm{H}_4\right)$
  • ✓
    Hydrazoic acid $\left(\mathrm{N}_3 \mathrm{H}\right)$
✓

Answer

Correct option: D.
Hydrazoic acid $\left(\mathrm{N}_3 \mathrm{H}\right)$
In $\ce{N_3H}​,$ the oxidation state of $N$ is $-\frac{1}{3}$​. Hence, it is not an integer.
The oxidation state of $N$ in $\mathrm{NH}_2 \mathrm{OH}, \mathrm{NH}_3$ and $\mathrm{N}_2 \mathrm{H}_4$ are $-1,-3$ and $-2$ respectively.
