If liquid A and B form ideal solutions

Give one example each for non-ideal solution showing positive deviation and non-ideal solution showing negative deviation.

Which of the following conditions are correct for real solutions showing negative deviation from Raoult's law?

Methanol and ethanol are liquids of similar nature, but a mixture of them is a non-ideal solution. Why?

Mathematically, this from of the Raoult's can be given as: P_("total"=P_(1)^(0)X_(1)+P_(2)^(0)X_(2) . Solution which obey Raoult's law over the entire range of concentration are known as ideal solution . two types of deviation from Raoult's law, that is, positive and negative deviations are observed. Azeotrons arise due to very large deviation from Raoult's law. then which of the following are correct
