    Among the following species, identify the isostructural pairs. \[[N{{F}_{3}},\,NO_{3}^{-},\,\,B{{F}_{3}},\,\,{{H}_{3}}{{O}^{+}}\,H{{N}_{3}}]\]

    A)  \[[N{{F}_{3}},\,NO_{3}^{-}]\,\,and\,\,[B{{F}_{3}},\,\,{{H}_{3}}{{O}^{+}}]\]

    B)  \[\left[ N{{F}_{3}},\,\,H{{N}_{3}} \right]\,\,and\,\,\left[ NO_{3}^{-},\,\,B{{F}_{3}} \right]\]

    C)  \[\left[ N{{F}_{3}},\,\,{{H}_{3}}{{O}^{+}} \right]\,\,and\,\,\left[ NO_{3}^{-},\,\,B{{F}_{3}} \right]\]

    D)  \[\left[ N{{F}_{3}},\,\,{{H}_{3}}{{O}^{+}} \right]\,\,and\,\,\left[ HN_{3}^{{}},\,\,B{{F}_{3}} \right]\]

    Correct Answer: C

    Solution :

    \[N{{F}_{3}}\] and \[{{H}_{3}}{{O}^{+}}\] have \[s{{p}^{3}}\] hybridisation. \[\operatorname{N}O_{3}^{-} and B{{F}_{3}}\] have \[s{{p}^{2}}\] hybridisation.
