Conversion of Acetylene into acetaldehyde

Explanation

To convert acetylene (ethyne) into acetaldehyde, we can follow these steps:

### Step 1: Hydration of Acetylene
1. **Start with Acetylene (C2H2)**: The molecular structure of acetylene consists of two carbon atoms triple-bonded to each other, with each carbon atom also bonded to one hydrogen atom.

2. **Add Water (H2O)**: The first step involves the addition of water to acetylene in the presence of a catalyst. The catalyst used is mercuric ion (Hg^2+) and sulfuric acid (H2SO4).

3. **Mechanism of Addition**:
