Q. Given below are two statements: Statement I: In Lucas test, primary, secondary and tertiary alcohols are distinguished on the basis of their reactivity with conc. HCl + $ZnCl_2$, known as Lucas Reagent. Statement II: Primary alcohols are most reactive and immediately produce turbidity at room temperature on reaction with Lucas Reagent. In the light of the above statements, choose the most appropriate answer from the options given below:
A) Statement I is incorrect but Statement II is correct.
B) Both Statement I and Statement II are correct.
C) Both Statement I and Statement II are incorrect.
D) Statement I is correct but Statement II is incorrect.
Explanation
[Solution] Tertiary alcohols react fastest and give immediate turbidity; primary alcohols do not give turbidity at room temperature. Statement II is incorrect. Answer (4).
