हिन्दीWhich of the following statements is CORRECT regarding a solution of two components A and B exhibiting positive deviation from ideal behaviour?
Correct answer · Option 2
Intermolecular attractive forces between \( A - A \) and \( B - B \) are stronger than those between \( A - B \).
Explanation
In solutions showing positive deviation, solute-solvent \( (A-B) \) interactions are weaker than solute-solute \( (A-A) \) and solvent-solvent \( (B-B) \) interactions, leading to expansion in volume and absorption of heat.
