Derive the structure of (i) 2-Chlorohexane, (ii) Pent-4-en-2-ol, (iii) 3- Nitrocyclohexene, (iv) Cyclohex-2-en-1-ol, (v) 6-Hydroxy- heptanal.

Explanation

To derive the structures of the given compounds, we will follow the IUPAC naming conventions and systematically build each structure based on the names provided.

### (i) 2-Chlorohexane
1. **Identify the parent chain**: The name "hexane" indicates a straight-chain alkane with 6 carbon atoms.
2. **Draw the carbon chain**: Create a linear chain of 6 carbon atoms (C1 to C6).
3. **Number the carbon chain**: Start numbering from one end to assign the lowest numbers to the substituents. Number from left to right (1 to 6).
4. **Add the substituent**: At carbon 2, add a chlorine (Cl) atom. The structure will look like this:
```
