Conversion of Acetylene into but-1-yne

Explanation

To convert acetylene (C₂H₂) into but-1-yne (C₄H₆), we can follow a two-step reaction process. Here’s how it can be done step by step:

### Step 1: Formation of Sodium Acetylide
1. **React Acetylene with Sodium**:
- Acetylene (C₂H₂) has acidic hydrogen atoms. When acetylene is treated with sodium (Na) in liquid ammonia (NH₃), it forms sodium acetylide (C₂H₃Na) and sodium amide (NaNH₂).
- The reaction is as follows:
\[
2 \, \text{C}_2\text{H}_2 + 2 \, \text{Na} \rightarrow 2 \, \text{C}_2\text{H}Na + \text{H}_2 \uparrow
