# The correct order of the oxidation states of nitrogen in

Question:

The correct order of the oxidation states of nitrogen in $\mathrm{NO}, \mathrm{N}_{2} \mathrm{O}, \mathrm{NO}_{2}$ and $\mathrm{N}_{2} \mathrm{O}_{3}$ is :

1. $\mathrm{NO}_{2}<\mathrm{N}_{2} \mathrm{O}_{3}<\mathrm{NO}<\mathrm{N}_{2} \mathrm{O}$

2. $\mathrm{NO}_{2}<\mathrm{NO}<\mathrm{N}_{2} \mathrm{O}_{3}<\mathrm{N}_{2} \mathrm{O}$

3. $\mathrm{N}_{2} \mathrm{O}<\mathrm{N}_{2} \mathrm{O}_{3}<\mathrm{NO}<\mathrm{NO}_{2}$

4. $\mathrm{N}_{2} \mathrm{O}<\mathrm{NO}<\mathrm{N}_{2} \mathrm{O}_{3}<\mathrm{NO}_{2}$

Correct Option: , 4

Solution:

Correct order of oxidation state of nitrogen in oxides of nitrogen is following

$\mathrm{N}_{2} \mathrm{O}<\mathrm{NO}<\mathrm{N}_{2} \mathrm{O}_{3}<\mathrm{NO}_{2}^{+4}$
