Select correct statement :

Options

A. The fundamental cause of all colligative properties is the higher entropy of the solution relative to that of the pure solvent.
B. The freezing point of hydrofluoride solution is larger than that of equimolal hydrogen chloride solution
C. `1M` glucose solution and `0.5M NaCl` solution are isotonic at a given temperature
D. All are coorect statements

Answer

D

Explanation

If `HF` hydrogen bonding is present so there is association of molecules due to this van't hoff factor is less, so depression in f.p decreases therefore f.p/ value is larger than `HC`. Similarly value of `i=2` for `NaCl` and `i=1` for Glucose.
