NEET Chemistry Raoult's Law MCQ Question
Which of the following statements about colligative properties is correct?
The elevation of boiling point is dependent on the number of solute particles in a solution.
In a solution with positive deviation, the solute-solvent interactions are stronger than solvent-solvent interactions.
Osmosis can be reversed by applying pressure greater than the osmotic pressure.
The boiling point of a solution is always lower than that of the pure solvent.
Correct Answer
Detailed Explanation
The elevation of boiling point is indeed directly proportional to the number of solute particles, as stated in the NCERT context. In contrast, option B is incorrect as positive deviation indicates weaker solute-solvent interactions. Option C is true but not the main focus of the question. Option D is incorrect because the boiling point of a solution is always higher than that of the pure solvent.
