This solution also shows positive deviation In case of negative deviations from Raoult’s law, the intermolecular
attractive forces between A-A and B-B are weaker than those between
A-B and leads to decrease in vapour pressure resulting in negative
deviations An example of this type is a mixture of phenol and aniline In this case the intermolecular hydrogen bonding between phenolic
proton and lone pair on nitrogen atom of aniline is stronger than the
respective intermolecular hydrogen bonding between similar
molecules
