How will you prepare benzoic acid from ethyl benzene ?

Explanation

To prepare benzoic acid from ethyl benzene, we can follow these steps:

### Step 1: Understand the Structures
- **Ethyl Benzene**: The structure of ethyl benzene consists of a benzene ring (C6H5) attached to an ethyl group (C2H5). The molecular formula is C8H10.
- **Benzoic Acid**: The structure of benzoic acid includes a benzene ring with a carboxylic acid group (-COOH) attached. The molecular formula is C7H6O2.

### Step 2: Identify the Reaction
- To convert ethyl benzene into benzoic acid, we need to oxidize the ethyl group (C2H5) to a carboxylic acid group (-COOH).
