The Lucas Test is a method for distinguishing between primary, secondary, and tertiary alcohols that is performed by mixing Lucas reagent with various alcohols. Learn the Lucas Test in Chemistry—how it distinguishes primary, secondary, and tertiary alcohols using Lucas reagent. Includes procedure, reactions, and results. Lucas' reagent is a solution of zinc chloride in hydrochloric acid used to classify alcohols by their reactivity. Learn how the Lucas test works, its history, and its limitations. An unknown alcohol is treated with Lucas reagent. Explain how you will determine whether the alcohol is primary, secondary or tertiary. Indicate by chemical equation the reaction
