    A) High bond energy of Xe - F Bond

    B) Low bond energy of F - F in \[{{F}_{2}}\] molecule

    C) Oxygen and xenon have almost similar ionization potentials.

    D) None of these.

    Correct Answer: C

    Solution :

    Oxygen and Xenon have almost similar ionization potential and size. Prompted by this and the reaction of \[{{O}_{2}}\] and\[Pt{{F}_{6}}\] \[{{O}_{2}}+Pt{{F}_{6}}\to {{O}_{2}}^{+}{{\left[ Pt{{F}_{6}} \right]}^{-}}\] Banlen prepared the first noble gas compound by the reaction. \[Xe+Pt{{F}_{6}}\to X{{e}^{+}}{{\left[ Pt{{F}_{6}} \right]}^{-}}\]
