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

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

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

    Correct Answer: C

    Solution :

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