What role does the molecular interaction play in a solution of alcohol and water?

Text Solution

Verified by Experts

In solution Hydrogen bonding between alcohal and water decreases. Magnitude of attractive forces tends to decrease and the solution shows positive deviation from Raoult.s law. This will lead to increase in vapour pressure of solution and decrease in its boiling point.
