Conversion of Acetaldehyde to Methane

Explanation

To convert acetaldehyde (CH3CHO) to methane (CH4), we can follow these steps:

### Step-by-Step Solution:

1. **Oxidation of Acetaldehyde:**
- Start with acetaldehyde (CH3CHO).
- Treat it with an oxidizing agent, such as potassium dichromate (K2Cr2O7) in the presence of sulfuric acid (H2SO4).
- This reaction oxidizes the aldehyde group (-CHO) to a carboxylic acid group (-COOH), resulting in acetic acid (CH3COOH).
