How are terminal alkynes distinguished and separated from internal alkynes?

Explanation

To distinguish and separate terminal alkynes from internal alkynes, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Structures**:
- Terminal Alkynes: These are alkynes where the triple bond is at the end of the carbon chain (e.g., 1-butyne).
- Internal Alkynes: These are alkynes where the triple bond is located between two carbon atoms in the chain (e.g., 2-butyne).
