Convert :
(i) Benzaldehyde to acetophenone

Explanation

To convert benzaldehyde (C6H5CHO) to acetophenone (C6H5COCH3), we can follow these steps:

### Step 1: Oxidation of Benzaldehyde
1. **Starting Material**: Begin with benzaldehyde (C6H5CHO).
2. **Oxidation Reaction**: Use a strong oxidizing agent like potassium permanganate (KMnO4) in the presence of sulfuric acid (H2SO4). This will oxidize the aldehyde group (CHO) to a carboxylic acid (COOH).
\[ \text{C6H5CHO} \xrightarrow{\text{KMnO4, H2SO4}} \text{C6H5COOH} \]
