  • question_answer
    Complete the following reactions by filling the appropriate choice.
    [A] \[6Xe{{F}_{4}}\,\,+\,\,12{{H}_{2}}O\,\,\to \,\,4Xe\,\,+\,\,2Xe{{O}_{3}}\,\,+\underline{\,\,(i)}\,\,+\,\,\underline{(ii)}\]
    [B] \[Xe{{F}_{6}}+3{{H}_{2}}O\to \underline{(iii)}+6HF\]
     

    A)
    (i) (ii) (iii)
    \[{{F}_{2}}\] \[{{H}_{2}}O\] \[XeO{{F}_{4}}\]

    B)
    (i) (ii) (iii)
    24HF \[3{{O}_{2}}\] \[Xe{{O}_{3}}\]

    C)
    (i) (ii) (iii)
    2HF \[2{{H}_{2}}O\] XeO

    D)
    (i) (ii) (iii)
    HF \[{{H}_{2}}O\] \[X{{e}_{2}}{{O}_{3}}\]

    Correct Answer: B

    Solution :

    \[6Xe{{F}_{4}}+12{{H}_{2}}O\to 4Xe+2Xe{{O}_{3}}+\underset{(i)}{\mathop{24HF}}\,+\underset{(ii)}{\mathop{3{{O}_{2}}}}\,\] \[Xe{{F}_{_{6}}}+3{{H}_{2}}O\to \underset{\left( iii \right)}{\mathop{Xe{{O}_{3}}}}\,+6HF\]
