Give a scheme of reactions that do not involve disproportionation of the oxides of nitrogen.

Explanation

To provide a scheme of reactions that do not involve disproportionation of the oxides of nitrogen, we need to focus on reactions where nitrogen oxides either undergo reduction or oxidation, but not both simultaneously. Here’s a step-by-step breakdown of such reactions:

### Step 1: Identify Nitrogen Oxides
First, we need to identify the common oxides of nitrogen. The most relevant ones are:
- Nitric oxide (NO)
- Nitrogen dioxide (NO2)
- Dinitrogen tetroxide (N2O4)
- Nitrous oxide (N2O)
