Write the products of reaction

Explanation

To solve the problem of writing the products of the given reaction, we will follow these steps:

### Step 1: Identify the Reactants
The reactants in this reaction are an amine (NH2) that is treated with nitrous acid (HNO2). The amine group will be converted into a diazonium salt.

### Step 2: Formation of Diazonium Salt
When the amine (NH2) is treated with HNO2, it forms a diazonium salt. The reaction can be represented as:
\[ R-NH2 + HNO2 \rightarrow R-N2^+ + H2O \]
