Chemistry - ALCOHOL & ETHER Question with Solution | TestHub
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. , 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:
NEET 2022 (Phase 1)
Options:
Answer:
Solution:
Lucas reagent helps in the distinction of primary, secondary and tertiary alcohols. A small quantity of unknown alcohol is added to Lucas reagent (anhyd. ) at room temperature and the mixture is shaken. A tertiary alcohol forms turbidity immediately, secondary alcohol forms turbidity within five minutes and primary alcohol shows no turbidity at room temperature.
So, Statement I is correct, but Statement II is incorrect.
