    The formation of \[O_{2}^{+}{{[Pt{{F}_{6}}]}^{-}}\]is the basis for the formation of xenon fluorides. This is because

    A) \[{{\text{O}}_{\text{2}}}\]   and \[~Xe\]   have   comparable electronegativities

    B) \[{{\text{O}}_{\text{2}}}\] and \[~Xe\]have comparable ionization enthalpies

    C) Both \[{{\text{O}}_{\text{2}}}\] and \[~Xe\]are gases

    D) None of the above

    Correct Answer: B

    Solution :

    The formation of \[O_{2}^{+}{{[Pt{{F}_{6}}]}^{-}}\] is the basis for the formation of xenon fluoride because the first ionization enthalpy of xenon gas \[(1170\,kJ\,mo{{l}^{-1}})\] is fairly close to that of oxygen \[(1175\,kJ\,mo{{l}^{-1}}).\]
