**Title: Understanding Organic Reactions: Formation of Alkyne**

**Introduction:**

In this exercise, we will explore the transformation of a vicinal dibromide into an alkyne using sodium amide (NaNH₂) as a base followed by treatment with an acid (H₃O⁺). This type of reaction is commonly encountered in organic synthesis to form carbon-carbon triple bonds.

**Reaction Details:**

1. **Starting Material:**
   - The initial compound is a six-carbon chain with two bromine atoms attached to adjacent (vicinal) carbon atoms (vicinal dibromide).

2. **Reagents:**
   - NaNH₂ (sodium amide), Δ (heat)
   - H₃O⁺ (acidic workup)

3. **Mechanism:**
   - The reaction proceeds through an elimination mechanism. Sodium amide (NaNH₂) acts as a strong base, abstracting hydrogen atoms and facilitating the removal of bromine atoms as bromide ions.
   - The elimination of two equivalents of HBr leads to the formation of an alkyne.

4. **Product:**
   - The final product is a linear alkyne, characterized by a carbon-carbon triple bond.

**Diagram Explanation:**

- **Reaction Scheme:** 
  - The starting dibromide on the left is transformed into an alkyne on the right.
  - The arrow indicates the reaction progression, driven by the applied reagents.

**Conclusion:**

This transformation from a vicinal dibromide to an alkyne highlights the utility of strong bases in organic synthesis, allowing chemists to build complex molecular architectures with precise control over functional group placement.
