An organic compound A of molecular formula `C_2H_6O ` on oxidation with alkaline `KMnO_4` gives a compound B with the same number of carbon atoms as in the molecule of A. Compound A is often used for sterilization of skin by doctors. Name the compounds A and B. Write the chemical equation involved in the formation of B from A.

Explanation

To solve the question, we need to identify the organic compounds A and B based on the given information and write the chemical equation for the reaction between them.

### Step-by-Step Solution:

1. **Identify Compound A**:
- The molecular formula given is \( C_2H_6O \).
- Two possible compounds can be derived from this formula:
- Ethyl alcohol (ethanol) \( CH_3CH_2OH \)
