    Intermolecular forces between Ti-hexane and n-heptane are nearly same as between hexane and heptane individually. When these two are mixed, which of the following is not true about the solution formed?

    A) It obeys Raoult's law, i.e. \[{{P}_{A}}={{x}_{A}}\,{{P}^{{}^\circ }}_{A}\]and\[{{P}_{B}}={{x}_{B}}\,P{{{}^\circ }_{B}}\]

    B) \[\Delta {{H}_{mixing}}\] is zero.

    C) \[\Delta {{V}_{mixing}}\]is zero.

    D) It forms minimum boiling azeotrope.

    Correct Answer: D

    Solution :

    Azeotropes are formed by the solutions which show deviations from ideal behaviour.
