Question:
Lucas test is associated with
Lucas test is associated with
Show Hint
Lucas test: 3° alcohol (immediate), 2° (5 mins), 1° (no reaction at RT).
Updated On: Apr 10, 2026
- aldehydes
- phenols
- carboxylic acids
- alcohols
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Reagent
Lucas reagent is a mixture of anhydrous $ZnCl_{2}$ and concentrated $HCl$.
Step 2: Reaction
It reacts with alcohols to form alkyl chlorides, which appear as turbidity.
Step 3: Application
The test is used specifically to distinguish between primary, secondary, and tertiary alcohols based on the speed of turbidity formation.
Final Answer: (d)
