    Using the following Latimer diagram for bromine,\[pH=0;\,\,Br{{O}_{2}}\xrightarrow{1.82\,V}\,BrO_{3}^{-}\xrightarrow{1.50\,V}\,\] \[HBr{{O}_{2}}\xrightarrow{1.595\,V}\,B{{r}_{2}}\xrightarrow{1.652\,V}B{{r}^{-}}\] The species undergoing dispropotionation is

    A)  \[Br{{O}_{4}}\]                   

    B)  \[BrO_{3}^{-}\]

    C)  \[HBrO\]                    

    D)  \[B{{r}_{2}}\]

    Correct Answer: C

    Solution :

     Hbr O will undergo disproportionation, because the potential to the left of it is less than that to the right.
