Mixture (s) showing positive deviation from Raoult's law at `35^(@)C` is (are)

Options

A. carbon tetrachloride + methanol
B. carbon disulphide + acetone
C. benzene + tolulene
D. phenol + aniline

Answer

A, B

Explanation

`[C Cl_(4)+CH_(3)OH]rarr` Shows positive deviation because when `C Cl_(4)` is mixed with methanol, some of intermolecular hydrogen bonds are broken.
`[CS_(2)+CH_(3)-overset(overset(O)("||"))(C)-CH_(3)]rarr` Mixing of polar and non-polar liquid gives solution of weaker intermolecular force showing positive deviation
[Benzene + Toluene] `rarr` Nearly ideal solution.
[Phenol + Aniline] `rarr` It shows negative deviation because they form strong intermolecular hydrogen bond when mixed.]
