How do you distinguish between `CH_3 CH=CHCI, CH_3 CH_2 CH_2 Cl and CH_2 =CH-CH_2 CI?`

Explanation

To distinguish between the compounds CH3CH=CHCl (allyl chloride), CH3CH2CH2Cl (n-butyl chloride), and CH2=CH-CH2Cl (vinyl chloride), we can use the reactivity of the chlorine atom in these compounds with silver nitrate (AgNO3). Here’s a step-by-step solution:

### Step 1: Understand the Compounds
- **CH3CH=CHCl (Allyl chloride)**: This compound has a double bond (alkene) and a chlorine atom attached to a carbon that is part of the double bond.
- **CH3CH2CH2Cl (n-Butyl chloride)**: This is a saturated alkane with a chlorine atom attached to a terminal carbon.
- **CH2=CH-CH2Cl (Vinyl chloride)**: This compound also has a double bond, but the chlorine is attached to a carbon that is part of the double bond.

### Step 2: React with Silver Nitrate (AgNO3)
