Arrange the following alcohols in order of increasing reactivity towards Lucas reagent :  2-butanol, 1-butanol, 2-methyl-2-propanol

Answer:

                The order of reactivity of alcohols towards Lucas reagent follows the sequence : \[3{}^\circ >2{}^\circ >1{}^\circ .\] Thus, the correct sequence of reactivity is : 2-methyl-2-propanol\[(3{}^\circ )\] > 2-butanol \[(2{}^\circ )\] > 1- butanol \[(1{}^\circ )\]
