How will you distinguish between but-1-yne and but-2-yne ?

Explanation

To distinguish between but-1-yne and but-2-yne, we can use the following steps:

### Step-by-Step Solution:

1. **Identify the Structures**:
- But-1-yne (C₄H₆) is a terminal alkyne, meaning it has a triple bond at the end of the carbon chain. Its structure is CH≡C-CH₂-CH₃.
- But-2-yne (C₄H₆) is a non-terminal alkyne, meaning the triple bond is located between two carbon atoms in the middle of the chain. Its structure is CH₃-C≡C-CH₃.
