Conversion of Ethyne into propyne

Explanation

To convert ethyne (C2H2) into propyne (C3H4), we can follow these steps:

### Step 1: Formation of Sodium Acetylide
1. Start with ethyne (C2H2).
2. React ethyne with sodium amide (NaNH2) to form sodium acetylide (C2H−Na+).
- The reaction can be represented as:
\[
\text{C}_2\text{H}_2 + \text{NaNH}_2 \rightarrow \text{C}_2\text{H}^-\text{Na}^+ + \text{NH}_3
