Question

non ideal solution show positive and negative deviation from raoult's law what are the deviations and why they are caused?​

Answer 1

Answer:

Deviations here means that the solution with (+ve deviation) have more vapour pressure than expected and in case of negative deviation it simply means that the vapour pressure of solution is less than that of expected.

Deviations are caused due to intermolecular attractions between solute and solvent (In pure or in impure state).
