How would you separate propene from propyne ?

Explanation

To separate propene from propyne, we can utilize their different reactivity with ammoniacal cuprous chloride (CuCl2 in ammonium hydroxide). Here’s a step-by-step solution:

### Step 1: Understand the Structures
- **Propene (C3H6)** has the structure: CH3-CH=CH2 (with a double bond).
- **Propyne (C3H4)** has the structure: CH3-C≡CH (with a triple bond).

### Step 2: React with Ammoniacal Cuprous Chloride
- Prepare a solution of ammonium hydroxide (NH4OH) and cuprous chloride (CuCl2).
