NEET Chemistry Raoult's Law MCQ Question
Which of the following statements regarding colligative properties and the van't Hoff factor is correct?
The van't Hoff factor is always greater than unity for all solutes.
The van't Hoff factor for a solute that dissociates is greater than unity, while for an associated solute, it is less than unity.
Colligative properties depend only on the nature of the solute, not on the number of solute particles.
The van't Hoff factor is not relevant to the calculation of colligative properties.
Correct Answer
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.
