alleryIn negative deviation the A-B interactions are, against the rest:
AWeaker ones
BThe same ones
CMissing ones
DStronger ones
Answer & Solution
Correct answer: D. Stronger ones
1. Negative deviation lowers the vapour pressure below prediction.
2. That happens when solute and solvent hold each other tightly.
3. So A-B interactions are stronger than A-A and B-B.
