How will you distinguish between allyl alcohol and n-propyl alcohol ?

Explanation

To distinguish between allyl alcohol (CH2=CH-CH2OH) and n-propyl alcohol (CH3-CH2-CH2OH), we can utilize Lucas reagent, which is a mixture of anhydrous zinc chloride (ZnCl2) and concentrated hydrochloric acid (HCl). Here’s a step-by-step solution:

### Step 1: Identify the Structures
- **Allyl Alcohol**: CH2=CH-CH2OH
- **n-Propyl Alcohol**: CH3-CH2-CH2OH

### Step 2: Understand the Reaction with Lucas Reagent
- Lucas reagent reacts differently with primary, secondary, and tertiary alcohols:
