### Chemical Nomenclature - IUPAC Naming

**Question:**
*Give the IUPAC name for this molecule.*

**Structure of the Molecule:**
The molecule is represented as follows:

```
CH3
 |
CH3CHCH2CH2CH
             \
              O
```
### Explanation of the Structure:
- The molecule consists of a six-carbon chain (hexane) with an aldehyde group (—CHO) at the first carbon.
- A methyl group (—CH3) is attached to the fourth carbon in the chain.

### IUPAC Name:
```
IUPAC name: 4-methylhexanal
```

**Breakdown of the IUPAC Name:**
- "Hex" indicates the main chain consists of six carbon atoms.
- "anal" indicates the presence of an aldehyde functional group.
- "4-methyl" indicates the position and presence of a methyl group attached to the fourth carbon of the main chain.

**Summary:**
The correct IUPAC name for the provided molecular structure is *4-methylhexanal*. This means that the main carbon chain is a six-carbon chain with an aldehyde group at one end, and a methyl group attached to the fourth carbon of this chain.
