Which of the following compound will give butanone on oxidation with alkaline `KMnO_(4)` solution ?

Options

A. Butan-1-ol
B. Butan-2-ol
C. Both of these
D. None of these.

Answer

To determine which compound will give butanone upon oxidation with alkaline KMnO₄ solution, we need to analyze the given options.

### Step-by-Step Solution:

1. **Understanding the Reaction**:
- Alkaline KMnO₄ is a strong oxidizing agent that can oxidize alcohols to aldehydes or ketones depending on the structure of the alcohol.

2. **Identifying the Compounds**:
- We need to check each compound to see if it can be oxidized to butanone (C₄H₈O).

3. **Analyzing Each Option**:
- **Option A: Butane-1-ol (CH₃CH₂CH₂CH₂OH)**:
- Butane-1-ol is a primary alcohol. When oxidized, it first converts to butanal (an aldehyde) and then further oxidizes to butanoic acid.
- Therefore, it does not yield butanone. **(Not the correct option)**

- **Option B: Butane-2-ol (CH₃CH₂CHOHCH₃)**:
- Butane-2-ol is a secondary alcohol. Upon oxidation with alkaline KMnO₄, it is converted directly to butanone (C₄H₈O).
- Therefore, this option yields butanone. **(Correct option)**

- **Option C: Butan-2-one (CH₃C(O)CH₂CH₃)**:
- Butan-2-one is already a ketone. Oxidation does not change its structure, so it cannot yield butanone. **(Not the correct option)**

- **Option D: None of the above**:
- Since we have identified option B as the correct answer, this option is also incorrect.

4. **Conclusion**:
- The compound that will give butanone on oxidation with alkaline KMnO₄ solution is **Butane-2-ol (Option B)**.

### Final Answer:
**Butane-2-ol (Option B)** will give butanone on oxidation with alkaline KMnO₄ solution.
