NEET Chemistry Van't Hoff Factor Assertion Reason Question
Assertion (A): The van't Hoff factor for acetic acid in benzene is less than unity. | Reason (R): Acetic acid undergoes dimerisation in benzene, reducing the number of particles.
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.
Correct Answer
Detailed Explanation
The van't Hoff factor is less than unity when solute molecules associate, as seen with acetic acid dimerisation in benzene, reducing particle count.
