In each of the following, sketch your estimates of the intermolecular potentials between the given molecules and their mixture on the same pair of axes.

(a) Chloroform is about 20% larger than acetone and about 10% stickier, but chloroform and acetone stick to one another much more strongly than they stick to themselves.

(b) You have probably heard that “oil and water don’t mix.” What does that mean in molecular terms? Let’s assume that oil can be characterized as benzene and that benzene is four times larger than water, but water is 10% stickier than benzene. If the ε₁₂ parameter is practically zero, that would represent that the benzene and water stick to themselves more strongly than to one another. Sketch this.
