    . Which of the following order for bond angles is correct?

    A) \[B{{F}_{3}}<N{{H}_{3}}<P{{F}_{3}}<CI{{F}_{3}}\]

    B) \[B{{F}_{3}}<N{{F}_{3}}<P{{F}_{3}}<CI{{F}_{3}}\]

    C) \[CI{{F}_{3}}<P{{F}_{3}}<N{{F}_{3}}<B{{F}_{3}}\]

    D) \[B{{F}_{3}}\approx N{{F}_{3}}<P{{F}_{3}}<CI{{F}_{3}}\]

    Correct Answer: C

    Solution :

    Bond angles of\[CI{{F}_{3}},\,\,P{{F}_{3}},\,\,N{{F}_{3}}\]and\[B{{F}_{3}}\]are \[{{80}^{o}},\,\,{{90}^{o}},\,\,{{101}^{o}},\,\,{{106}^{o}}\]and\[{{120}^{o}}\]respectively.
