The oxidation states of nitrogen in

Question:

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

  1. $\mathrm{NO}_{3}^{-}>\mathrm{NO}_{2}>\mathrm{NO}>\mathrm{N}_{2} \mathrm{O}$

  2. $\mathrm{NO}_{2}>\mathrm{NO}_{3}^{-}>\mathrm{NO}>\mathrm{N}_{2} \mathrm{O}$

  3. $\mathrm{N}_{2} \mathrm{O}>\mathrm{NO}_{2}>\mathrm{NO}>\mathrm{NO}_{3}^{-}$

  4. $\mathrm{NO}>\mathrm{NO}_{2}>\mathrm{N}_{2} \mathrm{O}>\mathrm{NO}_{3}^{-}$


Correct Option: 1

Solution:

The oxidation states of Nitrogen in following molecules are as follows

$\mathrm{NO}_{3}^{-} \rightarrow+5$

$\mathrm{NO}_{2} \rightarrow+4$

$\mathrm{NO}^{2} \rightarrow+2$

$\mathrm{~N}_{2} \mathrm{O} \rightarrow+1$
