    In the reaction \[2KMn{{O}_{4}}+16HCl\xrightarrow{{}}5C{{l}_{2}}+2MnC{{l}_{2}}+2KCl+8{{H}_{2}}O\] the reduced product

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

    B)  \[KCl\]          

    C)  \[HCl\]                       

    D)  \[MnC{{l}_{2}}\]

    Correct Answer: D

    Solution :

        \[\overset{+7}{\mathop{KMn{{O}_{4}}}}\,+\overset{-1}{\mathop{HCl}}\,\xrightarrow{{}}\overset{0}{\mathop{C{{l}_{2}}}}\,+\overset{+2}{\mathop{MnC{{l}_{2}}}}\,+KCl+{{H}_{2}}O\] Oxidation number of \[Mn\] decreases, hence \[KMn{{O}_{4}}\]has been reduced to \[MnC{{l}_{2}}.\] Thus the reduced product is \[MnC{{l}_{2}}.\]
