Acetaldehyde to acetone

Explanation

To convert acetaldehyde (CH3CHO) to acetone (CH3C(=O)CH3), we can follow these steps:

### Step 1: Oxidation of Acetaldehyde
- **Starting Material**: Acetaldehyde (CH3CHO)
- **Reagent**: Potassium dichromate (K2Cr2O7) in the presence of sulfuric acid (H2SO4)
- **Reaction**: When acetaldehyde is oxidized, it is converted to acetic acid (CH3COOH).

**Chemical Equation**:
