    Ozonised oxygen can be obtained from\[{{H}_{2}}O\]by the action of

    A)  conc. \[{{H}_{2}}S{{O}_{4}}\]    

    B)  \[KMn{{O}_{4}}\]

    C)  \[MnSO_{4}^{2-}\]         

    D)  \[{{F}_{2}}\]

    Correct Answer: D

    Solution :

     Fluorine reacts vigorously with water giving \[{{O}_{2}}\]and\[{{O}_{3}}\]mixture, known as ozonised oxygen. \[2{{F}_{2}}+2{{H}_{2}}\text{O}\xrightarrow[{}]{{}}4HF+{{O}_{2}}\] \[3{{F}_{2}}+3{{H}_{2}}\text{O}\xrightarrow[{}]{{}}6HF+{{O}_{3}}\]
