    Among the following species, identify the isostructural pairs, \[N{{F}_{3}},\,\,NO_{3}^{-},\,\,B{{F}_{3}},\,\,{{H}_{3}}{{O}^{+}},\,\,H{{N}_{3}}\]     [IIT 1996]

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

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

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

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

    Correct Answer: C

    Solution :

                    [\[N{{F}_{3}}\] and \[{{H}_{3}}{{O}^{+}}\]] are pyramidal while [\[NO_{3}^{-}\] and \[B{{F}_{3}}\]] are planar. Hence answer C is correct.
