NEET 2021 Chemistry Colligative Properties MCQ Question
The following solutions were prepared by dissolving 10 g of glucose (C₆H₁₂O₆) in 250 ml of water (P₁), 10 g of urea (CH₄N₂O) in 250 ml of water (P₂) and 10 g of sucrose (C₁₂H₂₂O₁₁) in 250 ml of water (P₃). The right option for the decreasing order of osmotic pressure of these solutions is:
P₂ > P₁ > P₃
P₁ > P₂ > P₃
P₂ > P₃ > P₁
P₃ > P₁ > P₂
Correct Answer
Detailed Explanation
Osmotic pressure depends on the number of particles in solution. Urea has the highest number of particles, followed by glucose and sucrose.
