    Three  elements \[A,\,\,B\]and\[C\]having reduction potential\[-1.5\],\[-0.5\] and \[1.5\] then arrange in correct order according to reducing power:

    A) \[A>B>C\]                          

    B) \[B>A>C\]

    C) \[C>B>A\]                          

    D) \[B>C>A\]

    Correct Answer: A

    Solution :

    A reducing agent is a substance which has a tendency to donate electrons in chemical reactions. Thus greater the reduction potential, less is the reducing power. So the correct order of their reducing power is. \[\begin{matrix}    A> & B> & C  \\    -1.5V & 0.5V & 1.5V  \\ \end{matrix}\]
