Answer 2

C. NaNO₃

Oxidation number:

Oxidation number, the total number of electrons that an atom either gains or loses in order to form a chemical bond with another atom.

Let's look at all the options one by one:

a. NH₃

Oxidation number of N in  NH₃ is -3.

b. N₂

Oxidation number of N in  N₂ is 0.

c. NaNO₃

Oxidation number of N in  NaNO₃ is +5.

d. $NO_2^-$

Oxidation number of N in  $NO_2^-$ is +3.

e. HNO₂

Oxidation number of N in HNO₂ is +3.

Therefore out of the following highest oxidation number of nitrogen will be in NaNO₃ which is +5.
