    Which of the following acts as an oxidizing agent?

    A)  \[HN{{O}_{3}}\]                              

    B)  \[C{{l}_{2}}\]

    C)  \[FeC{{l}_{3}}\]               

    D)  All of these

    Correct Answer: D

    Solution :

                    \[HN{{O}_{3}},C{{l}_{2}}\]and\[FeC{{l}_{3}}\]can accept electrons and can decrease their oxidation numbers and hence, all these substances act as oxidizing agents. \[\overset{+5}{\mathop{HN{{O}_{3}}}}\,\xrightarrow[{}]{{}}\overset{+4}{\mathop{N{{O}_{2}}}}\,\]or \[\overset{+2}{\mathop{NO}}\,\] \[\overset{0}{\mathop{C{{l}_{2}}}}\,\xrightarrow[{}]{{}}\overset{-1}{\mathop{2Cl}}\,\] \[\overset{+3}{\mathop{FeC{{l}_{3}}}}\,\xrightarrow[{}]{{}}\overset{+2}{\mathop{FeC{{l}_{2}}}}\,\]
