Which one of the following is an example of a liquid mixture showing positive deviations from Raoult's law ?

H-bonds in ${\mathrm{C}}_2{\mathrm{H}}_5\mathrm{OH}$ are weakened by the addition of CS₂.

Let A = ${\mathrm{C}}_2{\mathrm{H}}_5\mathrm{OH}$ and B = CS₂

Magnitude of A-B interactions are weaker than A-A and B-B .

It shows positive deviations from Raoult's law.

V. P of the a mixture is higher than expected.

$\therefore$BP of the mixture is lesser than any of the two components.

It is a minimum boiling azeotrope.
