Conversion of Ethyne into Propionic acid

Explanation

To convert ethyne (C2H2) into propionic acid (C3H6O2), we can follow these steps:

### Step 1: Hydrogenation of Ethyne
- **Reaction**: Ethyne (C2H2) is treated with hydrogen gas (H2) in the presence of a nickel (Ni) catalyst at a temperature of 250°C.
- **Equation**:
\[ \text{C}_2\text{H}_2 + \text{H}_2 \xrightarrow{\text{Ni, 250°C}} \text{C}_2\text{H}_4 \]
