Hydration of which of the given compounds leads to the formation of 2-methylpropan-2-ol?

Options

A. 2-methylpropane
B. 1-bromopropane
C. 2-methylpropene
D. Propene

Answer

To determine which compound's hydration leads to the formation of 2-methylpropan-2-ol, we need to analyze the hydration process of the given compounds.

### Step-by-Step Solution:

1. **Understanding Hydration**: Hydration is a chemical reaction where water (H2O) is added to a compound. In the case of alkenes, this involves the addition of H and OH across the double bond.

2. **Identifying the Target Compound**: The target compound is 2-methylpropan-2-ol, which has the structure:
- A propane backbone (3 carbon atoms).
- A hydroxyl group (OH) attached to the second carbon.
- Two methyl groups (CH3) also attached to the second carbon.

3. **Analyzing the Given Compounds**: We need to check which of the provided compounds can undergo hydration to yield 2-methylpropan-2-ol.

4. **Evaluating Compound A (Methylpropane)**:
- Methylpropane is an alkane (no double bond), so it cannot undergo hydration to form an alcohol.
- **Conclusion**: Not suitable.

5. **Evaluating Compound B (Another Alkane)**:
- Similar to compound A, this is also an alkane without a double bond.
- **Conclusion**: Not suitable.

6. **Evaluating Compound C (2-Methylpropene)**:
- 2-Methylpropene has a double bond between the second and third carbon atoms.
- When water is added, the H+ from water will attach to one of the carbons in the double bond, forming a carbocation at the more stable position (the second carbon).
- The OH- will then attach to the same carbon, leading to the formation of 2-methylpropan-2-ol.
- **Conclusion**: Suitable.

7. **Evaluating Compound D (Propene)**:
- Propene has a double bond between the first and second carbon atoms.
- Hydration of propene would lead to the formation of propan-2-ol, not 2-methylpropan-2-ol.
- **Conclusion**: Not suitable.

8. **Final Conclusion**: The only compound that leads to the formation of 2-methylpropan-2-ol upon hydration is **Compound C (2-methylpropene)**.
