Question

In Lucas test an alcohol react immediately and gives insoluble chloride. The alcohol is (A)  CH3OH  (B)  CH3CH2OH  (C)  (CH3)2CHOH  (D)  (CH3)3COH

In Lucas test, alcohol reacts with cone.

H Cl

in anhy

Z n C 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} CO H

.
