When an organic compound X is warmed with alkaline solution of `KMnO_4` a new compound Y is formed which smells of vinegar. On heating compounds X and Y with a few drops of concentrated sulphuric acid another compound Z is formed. Name the compound X and Y

Explanation

To solve the question, we need to identify the organic compounds X and Y based on the given reactions and characteristics.

### Step-by-Step Solution:

1. **Identify Compound X**:
- The question states that compound X is warmed with an alkaline solution of KMnO4, which is a strong oxidizing agent.
- When alcohols are oxidized by alkaline KMnO4, they typically form carboxylic acids.
- Given that the resulting compound Y has a smell of vinegar, we know that vinegar is acetic acid (ethanoic acid).
