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.
