Given below are two statements:
Statement I: In Lucas test, primary, secondary and tertiary alcohols are distinguished on the basis of their reactivity with cone. HCl + ZnCl2, 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:

Given below are two statements:Statement I: In Lucas test, primary, se...
Explanation:
Statement I:
- Lucas test is used to distinguish between primary, secondary, and tertiary alcohols based on their reactivity with Lucas Reagent (cone. HCl + ZnCl2).
- In Lucas test, tertiary alcohols react immediately with Lucas Reagent, forming a cloudy solution within seconds.
- Secondary alcohols show a slower reaction compared to tertiary alcohols, with the formation of a cloudy solution within a few minutes.
- Primary alcohols are the least reactive and require a longer reaction time or heating to form a cloudy solution when reacted with Lucas Reagent.
Statement II:
- This statement implies that primary alcohols are the most reactive and immediately produce turbidity at room temperature when reacted with Lucas Reagent, which is incorrect.
- In reality, primary alcohols are the least reactive among the three types and require more time or heating to show a positive test with Lucas Reagent.
Conclusion:
- Therefore, Statement I is correct as it explains the correct order of reactivity of primary, secondary, and tertiary alcohols in Lucas test, while Statement II is incorrect in stating that primary alcohols are the most reactive.

1° 2° 3° Alcohol are distinguished by Lucas test on the basis of the time taken for turbidity to appear
Reactivity of alcohol towards Lucas reagent
⇒ 3° > 2° > 1° Alcohol
Reactivity of alcohol towards Lucas reagent
⇒ 3° > 2° > 1° Alcohol
