    Three elements A, B and C having reduction potential \[-1.5,-0.5\] and \[1.5\,V\]respectively then  arrange them 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 :

    Key Idea: Greater the reduction potential, less is reducing power. Given reduction potential of\[A=-\text{ }1.5V\] reduction potential of \[B=-\text{ }0.5\text{ }V\] reduction potential of \[C=+\text{ }1.5\text{ }V\] \[\therefore \] The correct order of reducing power is \[A>B>C\]
