NEET Chemistry Raoult's Law MCQ Question
Type: MCQ-conceptual-Medium-Class 12
Which of the following statements regarding colligative properties and the van't Hoff factor is correct?
A
The van't Hoff factor is always greater than unity for all solutes.
B
The van't Hoff factor for a solute that dissociates is greater than unity, while for an associated solute, it is less than unity.
C
Colligative properties depend only on the nature of the solute, not on the number of solute particles.
D
The van't Hoff factor is not relevant to the calculation of colligative properties.
Correct Answer
Option B
Detailed Explanation
The van't Hoff factor (i) reflects the number of particles in solution. For dissociating solutes, i > 1, while for associating solutes, i < 1, as mentioned in the NCERT context on colligative properties and the van't Hoff factor.
