Write the relevant equation to convert acetic acid to acetone.

Explanation

To convert acetic acid (CH₃COOH) to acetone (CH₃COCH₃), we can follow a series of steps that involve the use of reagents and chemical reactions. Here’s a step-by-step breakdown of the process:

### Step 1: Convert Acetic Acid to Acetyl Chloride
1. **Starting Material**: Acetic Acid (CH₃COOH)
2. **Reagent**: Thionyl Chloride (SOCl₂) or Phosphorus Pentachloride (PCl₅)
3. **Reaction**: The hydroxyl group (-OH) of acetic acid is replaced by a chlorine atom (-Cl) to form acetyl chloride (CH₃COCl).

**Equation**:
