Question

What is the oxidation number/state of nitrogen in $NCl{}_3$ ?

Answer 1

1. Oxidation number is the hypothetical charge on the atom that provides an idea of which atom is oxidized or getting reduced in the reaction.

2. Oxidation number of chlorine is -1.

3. Now we have to calculate the oxidation number of nitrogen N.

4. Let the oxidation number of nitrogen be $x$

5. $\left(Oxidationnumberofnitrogen\right)\times 1+\left(Oxidationnumberofchlorine\right)\times 3=0$

6. $\left(x\right)\times 1+(-1)\times 3=0$

7. $x=+3$

The oxidation number of Nitrogen in $NCl{}_3$ is +3
