    Which of the following is planar?

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

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

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

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

    Correct Answer: D

    Solution :

                    \[Xe{{F}_{4}}\]has square planar structure. It involves \[s{{p}^{3}}{{d}^{2}}\]hybridisation of xenon which adopts octahedral geometry in which two positions are occupied by lone pairs.
