    Among the following species, identify the iso- structural pairs \[{{\operatorname{NF}}_{3}}, N{{O}_{3}}^{-}, B{{F}_{3}} {{H}_{3}}{{O}^{+}}, H{{N}_{3}}\]

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

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

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

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

    Correct Answer: C

    Solution :

    \[{{\operatorname{NF}}_{3}} and {{H}_{3}}{{O}^{+}}\] have \[s{{p}^{3}}\] hybridisation; \[N{{O}_{3}}\] and \[B{{F}_{3}}\] have sp2 hybridisation.
