Chemistry-Raoult's Law
NEET Chemistry Raoult's Law Assertion Reason Question
Type: Assertion Reason-assertion-Medium-Class 12
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.
A
Both A and R are true, and R is the correct explanation of A.
B
Both A and R are true, but R is not the correct explanation of A.
C
A is true but R is false.
D
A is false but R is true.
Correct Answer
Option A
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.
