    The oxidation number of O in \[\text{O}{{\text{F}}_{\text{2}}}\]is

    A) \[-2\]                    

    B)         \[+\,1\]                              

    C)         \[+\,2\]                              

    D)         \[-1\]

    Correct Answer: C

    Solution :

    Let the oxidation state of O in \[\text{O}{{\text{F}}_{\text{2}}}\]is \[x.\] \[O{{F}_{2}}\]                                 \[x+(-1)\times 2=0\]                                 \[x-2=0\] \[\therefore \]                  \[x=+\,2\]
