Complete the following reactions and write main products : (i) `CH_(3)CONH_(2)+HNO_(2)to`

Explanation

To complete the reaction of `CH₃CONH₂` (acetamide) with `HNO₂` (nitrous acid), we can follow these steps:

### Step 1: Identify the Reactants
The reactants are acetamide (`CH₃CONH₂`) and nitrous acid (`HNO₂`).

### Step 2: Understand the Reaction Mechanism
When acetamide reacts with nitrous acid, the amine group (`-NH₂`) in acetamide is converted into a diazonium ion. This is a key step in the mechanism.
