    Which one of the following reaction of xenon compounds is not feasible?

    A) \[Xe{{O}_{3}}+6HF\to Xe{{F}_{6}}+{{H}_{2}}O\]

    B) \[3Xe{{F}_{4}}+6{{H}_{2}}O\to 2Xe+Xe{{O}_{3}}+12HF+1.5{{O}_{2}}\]

    C) \[2Xe{{F}_{2}}+2{{H}_{2}}O\to 2Xe+4HF+{{O}_{2}}\]

    D) \[Xe{{F}_{6}}+RbF\to Rb[Xe{{F}_{7}}]\]

    Correct Answer: A

    Solution :

    [a] \[Xe{{F}_{6}}\] has much tendency to hydrolyze. The reverse reaction is more spontaneous. \[Xe{{F}_{6}}+3{{H}_{2}}O\to Xe{{O}_{3}}+6HF\]
