Question

When ethanol mixes in cyclohexane, the intermolecular forces reduces between ethanol molecule. In this, liquid pair shows :

• A. positive deviation from Raoult's law
• B. negative deviation from Raoult's law
• C. no deviation from Raoult's law
• D. decrease in volume

Answer 1

The correct option is A positive deviation from Raoult's law

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.
