    Azeotropic mixture of two liquids has boiling point higher than either of them when it

    A)  is saturated solution

    B)  shows positive deviation from Raoults law

    C)  shows negative deviation from Raoults law

    D)  shows no deviation

    E)  Both (a) and (b)

    Correct Answer: C

    Solution :

                    Azeotropic mixture of two liquids has boiling point higher than either of them when it shows negative deviation from Raoults law. Then, the mixture will take time to boil, i.e. its boiling point will become more, e.g. \[HN{{O}_{3}}\](68%) + water (32%).
