NEET Chemistry Raoult's Law Assertion Reason Question
Assertion (A): Ethanol-water mixture forms an azeotrope that cannot be separated by fractional distillation.
Reason (R): Azeotropes exhibit a constant boiling point as they have the same composition in liquid and vapor phases.
Both A and R are true, and R is the correct explanation of A.
Both A and R are true, but R is not the correct explanation of A.
A is true but R is false.
A is false but R is true.
Correct Answer
Detailed Explanation
An azeotrope, such as the ethanol-water mixture, has the same composition in both liquid and vapor phases, resulting in a constant boiling point, which prevents separation by fractional distillation.
