Question:

 Intermolecular forces between two benzene molecules are near to 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 a minimum boiling azeotrope.

(iv) These will not form the ideal solution.

Solution:

Option (iii) These will form a minimum boiling azeotrope and (iv) These will not form the ideal solution are the answers.
