Answer 1

the mixtures that show negative deviation from Toyota law up

Answer 2

Answer:

If the solute A-A bond and solvent B-B is weaker than A-B bond i.e. solute and solvent are tightly bound to each other as they are to themselves, then the solution will show a negative deviation from Raoult's law because the solvent molecules will not find it easier to escape from solution into the gas phase.
