Question

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 +ZnCl₂, knowns 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 correct
• B. Both statement I and Statement II are incorrect
• C. Statement I is correct but Statement II is incorrect
• D. Statement I is incorrect but statement II is correct

Answer 1

The Correct Option is C

Alcohols reactivity: \(3° > 2° > 1°\)
S-I is correct but S-II is incorrect as \(3°\) alcohol produces the most stable carbocation and thus it is most reactive with Lucas reagent.
