    Which are true statements among the following?

    A) \[I_{3}^{+}\] has bent structure

    B) \[Xe{{F}_{2}}\] and \[C{{O}_{2}}\] has same shape

    C) \[S{{F}_{4}}\] is sea-saw structure whereas \[IC{{l}_{3}}\] is T-shaped

    D) All of these

    Correct Answer: D

    Solution :

    [A] \[I_{3}^{+}=\frac{[7+2-1]}{2}=s{{p}^{3}}\]
    Hybridisation with 2 lone pair
    [B] \[Xe{{F}_{2}}\] \[s{{p}^{3}}d\] linear structure
    (3 lone pair +2B.P)
    \[O=C=O\]has same shape
    \[s{{p}^{3}}d\,\,1\,\,\ell .p\] + 3 B.P. = Sea saw structure
    \[\therefore \] All are correct.
