How will you convert ethanol to 1,1-dichloroethane ?

Explanation

To convert ethanol (CH3CH2OH) to 1,1-dichloroethane (CH3CCl2H), we can follow these steps:

### Step 1: Oxidation of Ethanol to Acetaldehyde
- **Reagent**: Use Pyridinium chlorochromate (PCC).
- **Reaction**: Ethanol (CH3CH2OH) reacts with PCC to form acetaldehyde (CH3CHO).

\[
\text{CH}_3\text{CH}_2\text{OH} \xrightarrow{\text{PCC}} \text{CH}_3\text{CHO}
