  • question_answer
    Of the interhalogen \[A{{X}_{3}}\] compounds, \[Cl{{F}_{3}}\] is most reactive but \[Br{{F}_{3}}\] has higher conductance in liquid state. This is because

    A) \[Br{{F}_{3}}\] has higher molecular mass.

    B) \[Cl{{F}_{3}}\] is more volatile.

    C) \[Br{{F}_{3}}\] dissociates into \[BrF_{2}^{+}\] and \[BrF_{4}^{-}\] most easily.

    D) Electrical conductance does not depend on concentration.

    Correct Answer: C

    Solution :

    [c] In liquid state \[Br{{F}_{3}}\] dissociates into \[BrF_{2}^{+}\]  and \[BrF_{4}^{-}\] ions most easily.
