Conversion of Benzaldehyde into benzene

Explanation

To convert benzaldehyde into benzene, we can follow these steps:

### Step 1: Convert Benzaldehyde to Benzoic Acid
- **Reaction**: Benzaldehyde (C6H5CHO) is oxidized to benzoic acid (C6H5COOH).
- **Reagent**: We can use Tollens' reagent (Ag(NH3)2OH), which is a mild oxidizing agent that oxidizes aldehydes to carboxylic acids.

**Chemical Equation**:
\[ \text{C}_6\text{H}_5\text{CHO} + [O] \rightarrow \text{C}_6\text{H}_5\text{COOH} \]
