Statement I: In Lucas test, primary, secondary and tertiary alcohols are distinguished on the basis of their reactivity with conc. , known as Lucas Reagent.Statement II: Primary alcohols are most reactive and immediately produce turbidity at room temperature on reaction with Lucas Reagent.

  1. A
    Both statement I and Statement II are correct.
  2. B
    Both statement I and Statement II are incorrect.
  3. C
    Statement I is correct but Statement II is incorrect.
  4. D
    Statement I is incorrect but statement II is correct.

Solution & Step-by-step Explanation

1. Statement I is correct: Lucas test is used for this distinction.2. Statement II is incorrect: Tertiary alcohols react immediately (due to stable carbocation). Secondary alcohols take minutes. Primary alcohols do not produce turbidity at room temperature at all (they require heating).
