NEET Chemistry Van't Hoff Factor MCQ Question
Type: MCQ-diagram based-Medium-Class 12
A diagram shows ethanoic acid molecules in benzene forming dimers due to hydrogen bonding. What is the expected value of the van't Hoff factor (i) for this system?
A
0.5
B
0
C
5
D
0
Correct Answer
Option A
Detailed Explanation
In the case of ethanoic acid in benzene, the molecules associate to form dimers, reducing the number of particles. Hence, the value of i is less than unity, specifically around 0.5.
