    In which of following pairs, the two species are isostructural?

    A)  \[BrO\overline{_{3}}\text{ }and\text{ }Xe{{O}_{3}}\] 

    B)   \[S{{F}_{4}}\text{ }and\text{ }Xe{{F}_{4}}\]

    C) \[S{{O}^{2-}}_{\text{3}}and\text{ }NO\overline{_{3}}\]  

    D)   \[B{{F}_{3}}\text{ }and\text{ }N{{F}_{3}}\]

    Correct Answer: A

    Solution :

    These both are pyramidal. All others have different geometries. For example: \[{{\operatorname{SiF}}_{4}}\]is trigonal bipyramidal and is square planar \[{{\operatorname{SO}}_{3}}^{2-}\]Cis pyramidal while N03 is trigonal planar \[{{\operatorname{BF}}_{3}}\]is trigonal planar and N?3 is pyramidal
