Give one chemical test to distinguish between the following pairs of compounds :
Acetone and benzaldehyde.

Explanation

To distinguish between acetone and benzaldehyde, we can use Tollens' reagent, which is a solution of ammoniacal silver nitrate. Here are the steps to perform the test:

### Step 1: Prepare Tollens' Reagent
- Mix silver nitrate (AgNO3) with ammonium hydroxide (NH4OH) to form Tollens' reagent. This reagent will appear as a clear solution.

### Step 2: Add the Compound
- Take two separate test tubes. In one test tube, add a few drops of acetone (CH3COCH3), and in the other test tube, add a few drops of benzaldehyde (C6H5CHO).
