    Xenon hexafluoride on partial hydrolysis produces compounds 'X' and 'Y'. Compounds 'X' and 'Y' and the oxidation state of Xe are respectively _______.                                                           [JEE Online 15-04-2018]

    A) \[XeO{{F}_{4}}(+6)\]and \[Xe{{O}_{2}}{{F}_{2}}(+6)\]

    B) \[XeO{{F}_{4}}(+6)\] and \[Xe{{O}_{3}}(+6)\]

    C) \[Xe{{O}_{2}}{{F}_{2}}(+6)\] and \[Xe{{O}_{2}}(+4)\]

    D) \[Xe{{O}_{2}}(+4)\] and \[Xe{{O}_{3}}(+6)\]

    Correct Answer: A

    Solution :

    Xenon hexafluoride on partial hydrolysis produces compounds \[XeO{{F}_{4}}\] and \[Xe{{O}_{2}}{{F}_{2}}\]. In the compounds \[XeO{{F}_{4}}\] and \[Xe{{O}_{2}}{{F}_{2}}\], the oxidation states of Xe are +6 and +6 respectively.             \[Xe{{F}_{6}}+{{H}_{2}}O\to XeO{{F}_{4}}+2HF\]             \[XeO{{F}_{4}}+{{H}_{2}}O\to Xe{{O}_{2}}{{F}_{2}}+2HF\]
