The distinction test for primary, secondary, and tertiary alcohol required to react with each of them is?
Correct answer: D. Conc. HCl and anhydrous ZnCl₂
- A. Conc. HCl and anhydrous SOCl₂
- B. Conc. HCl and anhydrous CaCl₂
- C. Conc. HCl and anhydrous PCl₃
- D. Conc. HCl and anhydrous ZnCl₂
Explanation
The Lucas test distinguishes primary, secondary and tertiary alcohols by their reactivity with Lucas reagent - concentrated HCl and anhydrous zinc chloride (ZnCl₂). Hence option D.

About Alcohols and Phenols
Alcohols are classified as primary, secondary or tertiary and studied through their hydrogen bonding, acidity, oxidation and reactions with active metals, acids and halogenating agents. Phenols require separate treatment because the hydroxyl group is attached to an aromatic ring, making their acidity and electrophilic substitution different from ordinary alcohols.
