The solution which deviate from ideal behaviour are called non ideal solution or real solutions.
They do not obey Raoult’s law over entire range of composition.
Solutions of above type show either positive or negative deviation from Raoult’s law.
The observed boiling point is found to be higher than the calculated value for the negative deviation.
Example:
When acetone and chloroform are mixed together a hydrogen bond is formed between them which increases inter molecular attraction between them and hence decreases the vapour pressure.
A low vapour pressure means a higher boiling point.
