Which of the following aqueous solution will show maximum vapour press...
The vapour pressure of a solution is dependent on the concentration and nature of the solute in the solution. The solution with the highest vapour pressure at a given temperature will have the lowest boiling point.
Explanation:
Boiling point elevation is a colligative property, which means it depends only on the number of solute particles in a solution and not on their identity. However, the vapour pressure of a solution is dependent on the nature of the solute.
- NaCl: NaCl is an ionic compound that dissociates into Na+ and Cl- ions in water. As a result, it will lower the vapour pressure of water due to ion-ion interactions. Therefore, it will show lower vapour pressure than pure water.
- CaCl2: CaCl2 is also an ionic compound that dissociates into Ca2+ and 2Cl- ions in water. It has more ions than NaCl, so it will have a greater effect on the vapour pressure of water. Therefore, it will show lower vapour pressure than NaCl solution.
- AlCl3: AlCl3 is a covalent compound that forms an ion-pair with water molecules. It will lower the vapour pressure of water due to ion-dipole interactions. But it will show less effect on vapour pressure than CaCl2, so it will show lower vapour pressure than CaCl2 solution.
- C12H22O11: C12H22O11 is a covalent compound that does not dissociate in water. It is a non-electrolyte that will not form ions in the solution. It will have no effect on the vapour pressure of water. Therefore, it will show the maximum vapour pressure at 300 K.
Conclusion:
- The aqueous solution of C12H22O11 will show maximum vapour pressure at 300 K.

Which of the following aqueous solution will show maximum vapour press...
If the soln will show maximum vapour pressure then it will show positive deviation from Roults Law and its boiling point is low.
Here concentration is same ,but i (vant Hoff factor) for glucose is less than NaCl,CaCl2 and AlCl3.
So ultimately its boiling point is low.
Hence D is correct.
