Give a chemical test and the reagents used to distinguish between the following :
'Ethylamine and diethylamine'

Explanation

To distinguish between ethylamine (C2H5NH2) and diethylamine (C2H5)2NH, we can use the Hinsberg test. Here’s a step-by-step solution:

### Step 1: Understand the Compounds
- **Ethylamine** is a primary amine (1° amine) with the structure C2H5NH2.
- **Diethylamine** is a secondary amine (2° amine) with the structure (C2H5)2NH.

### Step 2: Prepare the Hinsberg Reagent
- The Hinsberg reagent is benzene sulfonyl chloride (C6H5SO2Cl). This reagent is used to react with amines.
