Give a chemical test to distinguish between each of the following pairs of compounds : 2
(i) Ethylamine and Aniline
(ii) Aniline and Benzylamine

Explanation

To distinguish between the pairs of compounds (i) Ethylamine and Aniline, and (ii) Aniline and Benzylamine, we can perform specific chemical tests based on their reactivity.

### Step-by-Step Solution:

#### (i) Distinguishing between Ethylamine and Aniline:

1. **Test Selection**: Use a diazonium salt for the test. Aniline, being an aromatic amine, will react with diazonium salts to form a colored azo dye, while ethylamine, being an aliphatic amine, will not react in the same way.
