MCQ
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
    Both Statement $I$ and Statement $II$ are incorrect.
  • Statement $I$ is correct but Statement $II$ is incorrect.
  • C
    Statement $I$ is incorrect but Statement $II$ is correct.
  • D
    Both Statement $I$ and Statement $II$ are correct.

Answer

Correct option: B.
Statement $I$ is correct but Statement $II$ is incorrect.
b
$1^{\circ}, 2^{\circ}, 3^{\circ} Alcohol$ are distinguished by Lucas test on the basis of the time taken for turbidity to appear

$[Image]$

Reactivity of alcohol towards Lucas reagent $\Rightarrow 3^{\circ}>2^{\circ}>1^{\circ} \text { Alcohol }$
