Mixture(s) showing positive deviation from Raoult's law at $35^{\circ} \mathrm{C}$ is(are)\

Question

Professor PC Thomas Classes · Answer

(a, b) : $\mathrm{CCl}_{4}+\mathrm{CH}_{3} \mathrm{OH}$ and $\mathrm{CS}_{2}+$ $\left(\mathrm{CH}_{3}ight)_{2} \mathrm{CO}$\ ( $A-B$ interactions are weaker than $A-A$ and $B-B$ interactions) shows positive deviation from Raoult's law. Benzene + toluene forms an ideal solution.\ Phenol + aniline ( $A-B$ interactions are stronger than $A-A$ and $B-B$ interactions) shows negative deviation from Raoult's law.\
