    Which of the following is planar [J & K  2005]

    A) \[Xe{{F}_{2}}\]

    B) \[Xe{{O}_{3}}F\]

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

    D) \[Xe{{F}_{4}}\]

    Correct Answer: D

    Solution :

    In the formation of \[Xe{{F}_{4}},s{{p}^{3}}{{d}^{2}}\] hybridisation occurs which gives the molecule an octahedral structure. The xenon and four fluorine atoms are coplanar while the two equatorial positions are occupied by the two lone pairs of electrons.
