Question
Intermolecular forces between two benzene molecules are nearly of same strength as those between two toluene molecules. For a mixture of benzene and toluene, which of the following are not true?
(i) ∆mix H = zero
(ii) ∆mix V = zero
(iii) These will form minimum boiling azeotrope.
(iv) These will not form ideal solution.

Solution
(iii) These will form minimum boiling azeotrope.
(iv) These will not form ideal solution.
Explanation:
∆Hmix = 0, ∆Vmix = 0 and benzene and toluene will form an ideal solution. Also, ideal solutions do not form minimum boiling azeotropes.
