Question

why alkyl chlorides r formed which being insoluble result in turbidity in the soln explain

how alcohols r soluble in lucas reagent explain both

Answer 1

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.

$ROH+HCl\stackrel{ZnC{l}_2}{\to }RCl+H_{2}O$

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.
