Option 1: NO

Nitric oxide (NO) has an oxidation state of +2 for nitrogen. This is because oxygen has an oxidation state of -2, and the overall charge of the molecule is 0. Since there is only one nitrogen atom in NO, its oxidation state is +2.

Option 2: NO2

Nitrogen dioxide (NO2) has an oxidation state of +4 for nitrogen. This is because there are two oxygen atoms in NO2, and each has an oxidation state of -2. The overall charge of the molecule is 0, so the oxidation state of nitrogen must be +4 to balance out the -4 from the two oxygen atoms.

Option 3: N2O

Nitrous oxide (N2O) has an oxidation state of +1 for nitrogen. This is because there are two nitrogen atoms in N2O, and the overall charge of the molecule is 0. Each nitrogen atom has an oxidation state of +1.

Option 4: N2O5

Dinitrogen pentoxide (N2O5) has the highest oxidation state of nitrogen among the given options. The oxidation state of nitrogen in N2O5 is +5. This is because there are five oxygen atoms in
