                    Which of the following two are isostructural?                                                                                    

    A)                 \[Xe{{F}_{2}},\,IF_{2}^{-}\]

    B)                 \[N{{H}_{3}},\,B{{F}_{3}}\]          

    C)                 \[CO_{3}^{2-},\,SO_{3}^{2-}\]   

    D)                 \[PC{{l}_{5}},\,IC{{l}_{5}}\]

    Correct Answer: A

    Solution :

                    Iso structural: Compounds having same structure and same hybridisation are known as isostructural species.                 Ex. \[Xe{{F}_{2}}\] and \[IF_{2}^{-}\] are \[s{{p}^{3}}d\]                 hybridised and both have linear shape.                 \[F-{{I}^{-}}-FF-Xe-F\]
