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.
