    Which of the following is oxidised in the given reaction? \[2HgC{{l}_{2}}+SnC{{l}_{2}}\to H{{g}_{2}}C{{l}_{2}}+SnC{{l}_{4}}\]

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

    B) \[SnC{{l}_{2}}\]                               

    C) \[SnC{{l}_{4}}\]                               

    D) \[Hg\]

    Correct Answer: B

    Solution :

    Mercury (a more electropositive element) is added as \[HgC{{l}_{2}}-\] Therefore, it is reduced. Chlorine (a more electronegative element) is added as \[SnC{{l}_{2}}-\] Therefore, it is oxidized.
