A) \[C{{H}_{3}}OH\]
B) \[C{{H}_{3}}C{{H}_{2}}OH\]
C) \[{{(C{{H}_{3}})}_{2}}CHOH\]
D) \[{{(C{{H}_{3}})}_{3}}COH\]
Correct Answer: D
Solution :
In Lucas test, alcohol reacts with cone. \[HCl\] in anhy \[ZnC{{l}_{2}}\] and convert into alkyl halide, which is insoluble in water and their appearance is indicated by the appearance of turbidity. Since, the order of reactivity of alcohol is \[tertiary>secondary>primary\] Hence, the Lucas test is immediately given by tertiary alcohol, ie, \[{{(C{{H}_{3}})}_{3}}COH\].
