Write structures of different dihalogen derivatives of propane.

Explanation

To find the different dihalogen derivatives of propane (C₃H₈), we need to consider the possible positions where the halogen atoms (X) can attach. The halogen can be any of the halogens such as Cl, Br, or I. Here, we will denote the halogen as "X" for generality.

### Step-by-Step Solution:

1. **Identify the Structure of Propane**:
- Propane has the molecular formula C₃H₈ and its structure can be represented as:
```
H H H
