Which of the following compounds 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 oxidation behavior of the given alcohols.

### Step-by-Step Solution:

1. **Identify the Compounds**: The question provides two compounds: butan-1-ol and butan-2-ol. We need to analyze their structures and oxidation products.

2. **Understand the Oxidation of Alcohols**:
- **Primary Alcohols**: When a primary alcohol (like butan-1-ol) is oxidized, it typically converts to an aldehyde and then further oxidizes to a carboxylic acid.
- **Secondary Alcohols**: A secondary alcohol (like butan-2-ol) can be oxidized to a ketone.

3. **Analyze Butan-1-ol**:
- Butan-1-ol (CH3-CH2-CH2-CHOH) is a primary alcohol.
- Upon oxidation with alkaline KMnO4, it will first convert to butanal (an aldehyde) and then further oxidize to butanoic acid (a carboxylic acid).
- Therefore, butan-1-ol will **not** yield butanone.

4. **Analyze Butan-2-ol**:
- Butan-2-ol (CH3-CH(OH)-CH2-CH3) is a secondary alcohol.
- Upon oxidation with alkaline KMnO4, it will convert to butanone (a ketone).
- Therefore, butan-2-ol **will** yield butanone.

5. **Conclusion**: Based on the analysis, butan-2-ol is the compound that will give butanone upon oxidation with alkaline KMnO4 solution.

### Final Answer:
The compound that will give butanone on oxidation with alkaline KMnO4 is **butan-2-ol**.
