Question:

In case of positive deviation from Raoult’s law, which of the following statement is correct?

Options:

A-B interactions are stronger than those between A-A or B-B

A-B interactions are equal to those between A-A or B-B

A-B interactions are weaker than those between A-A or B-B

None of these

Correct Answer:

A-B interactions are weaker than those between A-A or B-B

Explanation:

In case of positive deviation from Raoult’s law, A-B interactions are weaker than those between A-A or B-B, i.e., in this case the intermolecular attractive forces between the solute-solvent molecules are weaker than those between the solute-solute and solvent-solvent molecules.
