Which of the two trans-but-2-ene or trans-pent-2.ene is non polar?

Explanation

To determine which of the two compounds, trans-but-2-ene or trans-pent-2-ene, is nonpolar, we need to analyze their molecular structures and the resulting dipole moments.

### Step-by-Step Solution:

1. **Identify the Structures**:
- **Trans-but-2-ene**: The structure can be represented as:
\[
\text{CH}_3\text{CH}=\text{CH}\text{CH}_3
