    Which of the following will replace \[B{{r}_{2}}\] from the aqueous solution having bromide ion?

    A)  \[C{{l}_{2}}\]                                    

    B)  \[I_{3}^{\bigcirc -}\]

    C)  \[{{I}_{2}}\]                                      

    D)  \[C{{l}^{\bigcirc -}}\]

    Correct Answer: A

    Solution :

    \[C{{l}_{2}}\] is stronger reducing agent than  \[B{{r}_{2}},\]hence chlorine replace \[B{{r}_{2}}\] from the aqueous solution having bromide ion. \[2NaBr+C{{l}_{2}}\xrightarrow{{}}2NaCl+B{{r}_{2}}\]
