Which amine in each of the following pairs is a stronger base? Give reasons.
` CH_3 CH_2 CH_2 NH_2 or CH_3 NH CH_2 CH_3`

Explanation

To determine which amine is a stronger base between CH₃CH₂CH₂NH₂ (1-aminopropane) and CH₃NHCH₂CH₃ (N-ethylmethanamine), we need to analyze the structures and the factors affecting their basicity.

### Step-by-Step Solution:

1. **Identify the Structures**:
- The first amine is **1-aminopropane** (CH₃CH₂CH₂NH₂).
- The second amine is **N-ethylmethanamine** (CH₃NHCH₂CH₃).
