Explanation

To convert the given compounds as per the question, we will follow the appropriate chemical reactions step by step. Here’s how to convert each compound:

### (i) Propene to Propan-2-ol
1. **Hydration of Propene**: Propene (C3H6) can be converted to propan-2-ol (C3H8O) through the hydration reaction.
2. **Reagents**: Use concentrated H2SO4 followed by water (H2O).
3. **Mechanism**:
- First, propene reacts with concentrated sulfuric acid to form isopropyl hydrogen sulfate (C3H7OSO3H).
- Then, hydrolysis of isopropyl hydrogen sulfate with water yields propan-2-ol.
