Question

In which of the following compounds the oxidation state of nitrogen is most negative?

• A. $N_2$
• B. $N_{2}O$
• C. $N{H}_3$
• D. $N{O}_2$
• E. $N{O}_3$

Answer 1

The correct option is C $N{H}_3$

In ammonia, $N{H}_3$, the oxidation state of nitrogen is most negative.
In ammonia, the oxidation state of nitrogen is -3.
The oxidation state of nitrogen in $N_2,N_{2}O,N{O}_{2}N{O}_3$ is 0, +1, +4 and +6 respectively.
