Question

An unknown alcohol is treated with the Lucas reagent ($conc. HCl$ and anhydrous $ZnCl_2$). Immediate turbidity is observed in the reaction mixture. Which of the following correctly describes the reacting alcohol and the kinetic mechanism of the substitution?

Prashant Kotian · Accepted Answer

Correct answer: C. Tertiary alcohols react immediately with the Lucas reagent to form an insoluble alkyl chloride, creating instant turbidity. Because the tertiary carbocation is highly stable, the reaction predominantly proceeds via an mechanism.
