But -1- yne and but -2- yne are treated with dil . `H_(2) SO_(4) ` in presence of `HgSO_(4)` at 330 K.

Explanation

To solve the problem regarding the reactions of but-1-yne and but-2-yne with dilute H₂SO₄ in the presence of HgSO₄ at 330 K, we will follow these steps:

### Step 1: Understand the Structures of But-1-yne and But-2-yne
- **But-1-yne** has the structure: CH₃C≡C–H (triple bond between the first and second carbon).
- **But-2-yne** has the structure: CH₃C≡CCH₃ (triple bond between the second and third carbon).

### Step 2: Reaction of But-1-yne with Dilute H₂SO₄ and HgSO₄
1. **Protonation**: The triple bond in but-1-yne is electron-rich and will react with H⁺ from dilute H₂SO₄.
