Show how to synthesize 3-decyne from acetylene along with necessary alkyl halides.

Explanation

To synthesize 3-decyne from acetylene (ethyne) using alkyl halides, we can follow these step-by-step instructions:

### Step 1: Starting Material
Start with acetylene (ethyne), which has the formula \( \text{C}_2\text{H}_2 \) and contains a triple bond between the two carbon atoms.

### Step 2: Deprotonation of Acetylene
Use sodium amide (\( \text{NaNH}_2 \)), a strong base, to deprotonate acetylene. This will remove one of the acidic hydrogens from acetylene, creating a nucleophile:
