Distinction between pairs of compounds
Ethylamine `(CH_(3)CH_(2)NH_(2))` and diethylamine `(CH_(3)CH_(2)NHCH_(2)CH_(3))`

Explanation

To distinguish between ethylamine `(CH₃CH₂NH₂)` and diethylamine `(CH₃CH₂NHCH₂CH₃)`, we can follow these steps:

### Step 1: Identify the Type of Amine
- **Ethylamine** is a primary amine because it has one alkyl group (ethyl) attached to the nitrogen atom.
- **Diethylamine** is a secondary amine because it has two alkyl groups (two ethyl groups) attached to the nitrogen atom.

### Step 2: Perform the Carbylamine Test
- The carbylamine test is a specific test for primary amines. When ethylamine reacts with chloroform `(CHCl₃)` in the presence of a strong base like potassium hydroxide `(KOH)`, it forms an isocyanide (carbylamine).
