Explanation:



Positive Deviation from Raoult's Law:

When two liquids form a binary solution and exhibit positive deviation from Raoult's law, it means that the vapor pressure of the solution is greater than what would be predicted by Raoult's law. This occurs when the intermolecular forces between the two components of the solution are weaker than the forces between like molecules.




Properties of Acetone and Carbon Disulphide:

Acetone (CH3COCH3) and carbon disulphide (CS2) have different boiling points. Acetone has a higher boiling point than carbon disulphide. This means that at a given temperature, acetone molecules have a lower vapor pressure compared to carbon disulphide molecules.




Effect on Boiling Temperature:

When acetone and carbon disulphide are mixed together, the intermolecular forces between the molecules of the two components are weaker than the forces between like molecules. This leads to positive deviation from Raoult's law.




Statement A: Boiling Temperature of Mixture:

The boiling temperature of a binary liquid solution depends on the composition of the solution. In the case of acetone and carbon disulphide, since acetone has a higher boiling point than carbon disulphide, the boiling temperature of the mixture will be less than the boiling temperature of acetone. Therefore, statement A is correct.




Statement B: Boiling Temperature of Azetropic Mixture:

An azeotropic mixture is a solution that boils at a constant temperature, with the composition of the vapor and liquid phases being the same. In the case of acetone and carbon disulphide, the boiling temperature of the azeotropic mixture will be less than the boiling temperature of carbon disulphide. Therefore, statement B is correct.




Statement C: Boiling Point Increase:

When a small amount of carbon disulphide is added to excess acetone, the intermolecular forces between the acetone molecules are disrupted. This results in an increase in the boiling point of the resulting mixture. Therefore, statement C is correct.




Statement D: Separation by Fractional Distillation:

Since acetone and carbon disulphide form a binary liquid solution with positive deviation from Raoult's law, it is not possible to completely separate the two components by simple fractional distillation. The mixture will boil at a temperature lower than the boiling point of acetone, making it difficult to achieve complete separation. Therefore, statement D is incorrect.




In conclusion, the correct statements are A, B, and C.

Statements (1) and (2) are correct because for a solution with a positive deviation from Raoult's law, the boiling point of the mixture is lower than that of either of the components.
Statement (3) is correct because if the mole fraction of the lower boiling component is decreased, the boiling point will increase.
Only statement (4) is incorrect as the components of azeotropic mixtures cannot be separated completely.
