Question

What is the range of the oxidation states shown by nitrogen in its oxides?

• A. $+1$ to $+3$
• B. $+2$ to $+4$
• C. $+1$ to $+2$
• D. $+1$ to $+5$

Answer 1

The correct option is D $+1$ to $+5$

Oxides of nitrogen:
1. Dinitrogen oxide $\left({\stackrel{+1}{N}}_{2}O\right)$
2. Nitrogen monooxide $\left(\stackrel{+2}{N}O\right)$
3. Dinitrogen trioxide $\left({\stackrel{+3}{N}}_2{O}_3\right)$
4. Nitrogen dioxide $\left(\stackrel{+4}{N}{O}_2\right)$
5. Dinitrogen tetraoxide $\left({\stackrel{+4}{N}}_2{O}_4\right)$
6. Dintrogen pentoxide $\left({\stackrel{+5}{N}}_2{O}_5\right)$

Hence, option (d) is the correct answer.
