Give simple chemical tests to distinguish between Butanal and butan-2-one.

Explanation

To distinguish between butanal (an aldehyde) and butan-2-one (a ketone), we can use simple chemical tests. Here is a step-by-step solution:

### Step 1: Identify the Compounds
- **Butanal**: It is an aldehyde with the structure CH3CH2CH2CHO.
- **Butan-2-one**: It is a ketone with the structure CH3COCH2CH3.

### Step 2: Perform the Tollens Test
- **Tollens Reagent**: This reagent is a solution of silver nitrate (AgNO3) in ammonia (NH3). It is used to test for aldehydes.
