The compound which reacts fastest with Lucas reagent at room temperature is

A
butan-1-ol
B
butan-2-ol
C
2-methyl propan-1-ol
Correct answer
D
2-methyl propan-2-ol

Solution

The order of reactivity of alcohols towards Lucas reagent is as Tertiary $\gt$ Secondary $\gt$ Primary Since 2-methyl propan-2-ol is a tertiary alcohol, hence it reacts fastest with Lucas reagent at room temperature.

Hence, the correct answer is option: 'D'.
