**Structural Representation of a Ketone**

This image shows the structural representation of a ketone molecule. The chemical structure is depicted as follows:

```
   O
  //
CH3 - CH2 - C - CH2 - CH3
```

### Explanation:

1. **Functional Group**: The central atom is carbon (C) and is double-bonded to an oxygen atom (O), which is the defining feature of the ketone functional group (carbonyl group).
2. **Carbon Chain**: The carbon atom (C) is bonded to two hydrocarbon chains:
   - On the left side: CH3 (methyl group) - CH2 (methylene group)
   - On the right side: CH2 (methylene group) - CH3 (methyl group)
   
This specific molecular structure corresponds to pentan-2-one, a simple ketone where the carbonyl group is situated on the second carbon atom of a five-carbon chain. 

By understanding this structural formula, students can learn how to identify and name ketones based on the position of the carbonyl group and the length of the carbon chain.
