Given the chemical tests to distinguish between the following pairs of compounds :
(i) Methylamine and Dimethylamine
(ii) Aniline and N - Methylamine

Explanation

To distinguish between the given pairs of compounds, we will perform specific chemical tests that highlight the differences in their reactivity.

### (i) Distinguishing between Methylamine and Dimethylamine

**Step 1: Perform the Carbylamine Test**
- Take a small amount of each amine (methylamine and dimethylamine) in separate test tubes.
- Add chloroform (CHCl3) and an alcoholic solution of potassium hydroxide (KOH) to each test tube.
- Heat the mixtures gently.
