JEE Main 2026 Chemistry question
Which of the following statements are not correct? A. For water, magnitude of is more than the magnitude of . B. The elevation in boiling point of water when a non-volatile solute is added to it is larger in magnitude than its depression in freezing point. C. Osmotic pressure measurement is preferred over any other colligative property to determine molar mass of proteins and polymers. D. The dimerised form of benzoic acid in benzene is C₆H₅−C(=O)−OH······O=C(−OH)−C₆H₅ (a single hydrogen bond drawn between the two molecules). Choose the correct answer from the options given below:
Solution
For water =0.512 and =1.86 K kg mol⁻¹, so < (A is not correct) and the boiling point elevation is smaller than the freezing point depression at the same molality
