    The reduction potential values of X, Y and Z are   \[-3.05\,V,-0.44\,V\]and\[~-0.83\,V\] respectively. Which of the following order is correct with respect to their reducing property?

    A) \[X>Y>Z\]       

    B) \[X>Z>Y\]

    C) \[Y>Z>X\]  

    D) \[~Z>Y>X\]

    Correct Answer: B

    Solution :

     More negative value of reduction potential shows the stronger reducing nature. The order of reduction potential values (with negative sign) of given elements is \[\underset{(-3.05)}{\mathop{X}}\,>\underset{(-0.83\,V)}{\mathop{Z}}\,>\underset{(-0.44\,V)}{\mathop{Y}}\,\] Thus, the order of reducing property is \[X>Z>Y\]
