Two sucrose solutions of the same molality prepared in different solvents will have the same freezing point depression.

(D) Statement $D$ is false.Freezing point depression is given by $\Delta T_f = K_f \times m$.Here,$K_f$ is the molal depression constant (cryoscopic constant),which depends on the nature of the solvent.Since the solvents are different,their $K_f$ values will be different,leading to different freezing point depressions even if the molality $m$ is the same.

Which one of the following statements is false?

A
Raoult's law for a mixture of two liquids states that the vapour pressure of a component over a solution is proportional to its mole fraction.
B
The osmotic pressure $(\pi)$ of a solution is given by the equation $\pi = iMRT$,where $M$ is the molarity of the solution.
C
The correct order of osmotic pressure for $0.01 \ M$ aqueous solutions of each compound is $BaCl_2 > KCl > CH_3COOH > Sucrose$.
D
Two sucrose solutions of the same molality prepared in different solvents will have the same freezing point depression.
