Write structures of different isomers corresponding to the molecular formula, `C_(3)H_(9)N.` Write IUPAC names of the isomers which will liberate nitrogen gas on treatment with nitrous acid.

Explanation

To solve the question, we need to identify the isomers of the molecular formula \( C_3H_9N \) and determine which of these isomers will liberate nitrogen gas when treated with nitrous acid.

### Step 1: Identify Isomers of \( C_3H_9N \)

1. **Primary Amines**:
- **Propane-1-amine**:
\[
\text{Structure: } CH_3-CH_2-CH_2-NH_2
