Reaction of alcohols with hydrogen halides (HX)


In Lucas test, alcohols react at different rates to form a turbid solution. A stable carbocation will produce turbidity much faster than an unstable carbocation.
A student treats the given 3 different alcohols with Lucas reagent and gets the following results.
Match the given alcohols with the correct amount of time taken to form turbidity.
Lucas reagent is a solution of concentrated HCl+ZnClA2.
