2-Propanone (acetone) can be obtained by Wacker's process starting with:

Options

A. Propyne
B. Propan-2-ol
C. Propene
D. Propanol-1-ol

Answer

To determine which compound can be converted to 2-Propanone (acetone) via Wacker's process, we need to analyze the options provided and understand the process itself.

### Step-by-Step Solution:

1. **Understanding Wacker's Process**:
- Wacker's process is an oxidation reaction where alkenes are converted to carbonyl compounds (aldehydes or ketones) in the presence of palladium catalysts and other reagents.
- The general reaction involves the oxidation of an alkene to produce a ketone or aldehyde.

2. **Identifying the Starting Material**:
- We need to identify which of the given options can be oxidized to form 2-Propanone (acetone).
- The structure of 2-Propanone is CH3COCH3, which indicates that it is a ketone.

3. **Analyzing the Options**:
- **Option A**: Propane-2-ol (isopropanol) - This is an alcohol, and while it can be oxidized to a ketone, it is not a suitable starting material for Wacker's process.
- **Option B**: Propene - This is an alkene and can be oxidized to form 2-Propanone.
- **Option C**: Propanol-1-ol - This is also an alcohol and not suitable for Wacker's process.
- **Option D**: Propene - This is the same as option B and is a valid starting material.
- **Option E**: An alkyne (not specified) - Alkynes cannot be directly converted to ketones via Wacker's process.

4. **Conclusion**:
- The only suitable starting material that can be oxidized to form 2-Propanone via Wacker's process is **Propene** (C3H6).
- Therefore, the correct answer is **Option B (Propene)**.

### Final Answer:
2-Propanone (acetone) can be obtained by Wacker's process starting with **Propene**.
