Solution
Lucas reagent is solution of anhydrous ZnCl2 in conc. HCl. This reagent is used for distinguishing between primary, secondary and tertiary alcohols.
This test is based on the formation of alkyl chloride from alcohol on reaction with HCl.
Alkyl chlorides are insoluble in water due to which turbidity appears in the solution.
The rate of reaction of alcohols with HCl follows the order: tertiary > secondary > primary
So, tertiary alcohols give turbidity immediately, secondary alcohols give turbidity in a few minutes while primary alcohols donot give develop any turbidity at room temperature.
