(1)“Lucas’ reagent” is a solution of anhydrous zinc chloride in concentrated hydrochloric acid. This solution is used to classify alcohols of low molecular weight. The reaction is a substitution in which the chloride replaces a hydroxyl group.
(2) Lucas reagent converts alcohols to alkyl chlorides: tertiary alcohols give an immediate reaction, indicated when the alcohol solution turns cloudy; secondary alcohols usually show evidence of reacting within five minutes; primary alcohols do not react to any significant extent. The order of reactivity of alcohols is: 3∘>2∘>1∘
Among the given alcohols, is a tertiary alcohol. So, it will react instantaneously with Lucas reagent.
