MCQ
When ethanol mixes in cyclohexane; cyclohexane reduces the intermolecular forces between ethanol molecule. In this, liquid pair shows
  • ✓
    Positive deviation by Raoult's law
  • B
    Negative deviation by Raoult's law
  • C
    No deviation by Raoult's law
  • D
    Decrease in volume
✓

Answer

Correct option: A.
Positive deviation by Raoult's law
a
Positive deviation from Raoult's law - force between $A-A$ and $B-B$ molecules is stronger than the force between $A-B$ molecules.

So, [$A$] is the right answer.
