Which amine with formula `C_(3)H_(9)N` has least boiling point as compared to its other functional isomers?

Explanation

To determine which amine with the formula \( C_3H_9N \) has the least boiling point compared to its other functional isomers, we can follow these steps:

### Step 1: Identify Possible Isomers
The molecular formula \( C_3H_9N \) can represent different structural isomers of amines. The possible isomers include:
1. **Primary amine**: Propylamine (\( CH_3CH_2CH_2NH_2 \))
2. **Secondary amine**: Isopropylamine (\( (CH_3)_2CHNH_2 \))
3. **Tertiary amine**: Trimethylamine (\( (CH_3)_3N \))
