An organic compound A having molecular formula `C_(2)H_(4)O_(2)` reacts witgh sodium metal and evolves a gas B which readily catches fire. A also reacts with ethanol in t he presence of concentrated sulphuric acid to form sweet smelling substance C used in making perfumes.
Write balanced chemical equations to represent
the evolution of B from compound A

Explanation

To solve the problem, we need to identify the organic compound A, which has the molecular formula C₂H₄O₂. This compound is acetic acid (CH₃COOH). When acetic acid reacts with sodium metal, it produces hydrogen gas (H₂), which is the gas B that readily catches fire.

### Step-by-Step Solution:

1. **Identify the Organic Compound A**:
- The molecular formula C₂H₄O₂ corresponds to acetic acid (CH₃COOH).

2. **Reaction of Acetic Acid with Sodium**:
