Carry out the following conversions :
Ethanol to acetone.

Explanation

To convert ethanol (C2H5OH) to acetone (C3H6O), we will follow a series of chemical reactions. Here’s a step-by-step breakdown of the process:

### Step 1: Oxidation of Ethanol to Acetaldehyde
- **Reaction**: Ethanol (C2H5OH) is oxidized to acetaldehyde (C2H4O).
- **Reagent**: Pyridinium chlorochromate (PCC) is used as the oxidizing agent.

**Chemical Equation**:
\[ \text{C}_2\text{H}_5\text{OH} \xrightarrow{\text{PCC}} \text{C}_2\text{H}_4\text{O} + \text{H}_2\text{O} \]
