    In which of the following pairs of molecules/ions, the central atoms have \[s{{p}^{2}}\] hydridisation?

    A) \[B{{F}_{3}}\]and\[NH_{2}^{-}\]

    B) \[NO_{2}^{-}\]and\[N{{H}_{3}}\]

    C) \[B{{F}_{3}}\]and\[NO_{2}^{-}\]

    D) \[NH_{2}^{-}\]and\[{{H}_{2}}O\]

    Correct Answer: C

    Solution :

    \[B{{F}_{3}}\] and \[NO_{2}^{-}\] are \[s{{p}^{2}}\] hybridised while \[N{{H}^{2}},\,\,N{{H}^{3}}\] and \[{{H}_{2}}O\] are \[s{{p}^{3}}\] hybridised.
