Give a test to distinguish between aldehyde and ketone.

Explanation

To distinguish between aldehydes and ketones, we can perform the Tollens test. Here’s a step-by-step solution:

### Step 1: Prepare the Tollens Reagent
- Tollens reagent is prepared by mixing silver nitrate (AgNO₃) with ammonia (NH₃) in a basic medium. The resulting complex is [Ag(NH₃)₂]⁺, which is the active component of the Tollens reagent.

### Step 2: Add the Sample
- Take the organic compound you want to test (either an aldehyde or a ketone) and add it to the prepared Tollens reagent.
