Ethanol to butan-2-one

Explanation

To convert ethanol (CH₃CH₂OH) to butan-2-one (CH₃C(=O)C₂H₅), we can follow these steps:

### Step 1: Oxidation of Ethanol
- **Reaction:** Ethanol (CH₃CH₂OH) is oxidized to acetaldehyde (ethanal, CH₃CHO).
- **Reagent:** Use an oxidizing agent such as Pyridinium chlorochromate (PCC) or potassium dichromate (K₂Cr₂O₇).

**Equation:**
\[ \text{CH}_3\text{CH}_2\text{OH} \xrightarrow{\text{PCC}} \text{CH}_3\text{CHO} \]
