Which of the following reaction is possible?
Properties such as boiling point, freezing point and vapour pressure of a pure solvent change when solute molecules are added to get homogeneous solution. These are called colligative properties. Applications of colligative properties are very useful in day-today life. One of its examples is the use of ethylene glycol and water mixture as anti-freezing liquid in the radiator of automobiles.

A solution $\mathrm{M}$ is prepared by mixing ethanol and water. The mole fraction of ethanol in the mixture is $0.9$ .

Given: Freezing point depression constant of water $\left(\mathrm{K}_{\mathrm{f}}^{\text {rate }}\right)=1.86 \mathrm{~K} \mathrm{~kg} \mathrm{~mol}^{-1}$

Freezing point depression constant of ethanol $\left(\mathrm{K}_{\mathrm{f}}^{\text {ethunol }}\right)=2.0 \mathrm{~K} \mathrm{~kg} \mathrm{~mol}^{-1}$

Boiling point elevation constant of water $\left(\mathrm{K}_{\mathrm{b}}^{\text {nate }}\right)=0.52 \mathrm{~K} \mathrm{~kg} \mathrm{~mol}^{-1}$

Boiling point elevation constant of ethanol $\left(\mathrm{K}_{\mathrm{b}}^{\text {ethanol }}\right)=1.2 \mathrm{~K} \mathrm{~kg} \mathrm{~mol}^{-1}$

Standard freezing point of water $=273 \mathrm{~K}$

Standard freezing point of ethanol $=155.7 \mathrm{~K}$

Standard boiling point of water $=373 \mathrm{~K}$

Standard boiling point of ethanol $=351.5 \mathrm{~K}$

Vapour pressure of pure water $=32.8 \mathrm{~mm} \mathrm{Hg}$

Vapour pressure of pure ethanol $=40 \mathrm{~mm} \mathrm{Hg}$

Molecular weight of water $=18 \mathrm{~g} \mathrm{~mol}^{-1}$

Molecular weight of ethanol $=46 \mathrm{~g} \mathrm{~mol}^{-1}$
