- AThe N-N bond in $\text{NH}_2\text{NH}_2$ is polar.
- B$\text{NH}_3$ and $\text{NH}_2\text{NH}_2$ have lone pairs of electrons but $\text{N}_2$ does not.
- CThe oxidation number of each nitrogen in $\text{NH}_2\text{NH}_2$ is $+2$.
- DThe reaction of nitrogen with hydrogen has a high activation energy.
