    The pair of species having identical shapes for molecules of both species is     AIEEE  Solved  Paper-2003

    A)                                         \[C{{F}_{4}},S{{F}_{4}}\]         

    B)                       \[Xe{{F}_{2}},C{{O}_{2}}\]                           

    C)       \[B{{r}_{3}},PC{{l}_{3}}\]        

    D)                       \[P{{F}_{5}},l{{F}_{5}}\]

    Correct Answer: B

    Solution :

    In \[C{{O}_{2}}\], C-atom is sp-hybridised thus it has linear structure.              In \[Xe{{F}_{2}},\,Xe\] is \[s{{p}^{3}}\]d hybridised with three lone-pairs of electrons on equatorial position. This minimizes repulsion hence it has also linear structure.
