QNEET-2022-Ch-375: NEET 2022 Chemistry - Class 12 NEET-2022-Ch-375 Solution: Given below are two statements: Statement I: In Lucas test…
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 + 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
Multiple Choice Options
- 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
Step-by-Step Verified Solution
Primary, secondary and tertiary alcohols can be differentiated by their reaction with (HCl + anhy ZnCl 2 ) Lucas reagent
_ 3 _ alcohol _ Z n C l 2 + H C l Immediate turbidity at room temperature
_ 2 _ alcohol _ Z n C l 2 + H C l Turbidity after 5 minutes at room temperature
_ 1 _ alcohol _ Z n C l 2 + H C l Do not gives turbidity at room temperature
