Identify the mixture that shows positive deviations from Raoult's Law
✓ Correct answer: c)
(CH3)2CO + CS2
Explanation
Mixing polar acetone with non-polar CS₂ weakens intermolecular attractions (A–B < A–A/B–B) → positive deviation from Raoult’s law.
The other pairs (acetone–chloroform, acetone–aniline, chloroform–benzene) form specific associations/H-bonding → negative deviation.
