Conversion of Benzaldehyde to Cyanobenzene

Explanation

To convert Benzaldehyde (C6H5CHO) to Cyanobenzene (C6H5CN), we will follow a series of reactions. Here’s a step-by-step breakdown of the process:

### Step 1: Oxidation of Benzaldehyde to Benzoic Acid
- **Reagents**: KMnO4 in alkaline medium
- **Reaction**: Benzaldehyde (C6H5CHO) is oxidized to Benzoic Acid (C6H5COOH).

**Chemical Equation**:
\[ C_6H_5CHO + [O] \rightarrow C_6H_5COOH \]
