What are non-ideal solutions ? Mention the reason for the negative dev – InterviewSolution

1.	What are non-ideal solutions ? Mention the reason for the negative deviation from the Raoult's law.
Answer» Solution :The solutions which do not obey Raoult.s Law over the ENTIRE range of CONCENTRATION and temperature ARECALLED as non-ideal solutions. The reason for the negative deviation from Raoult.s law is that the INTERMOLECULAR ATTRACTIVE forces betweenA-A & B-B are weaker than those between A-B and leads to decrease in vapour pressure.
