    \[{{E}^{o}}\] for \[F{{e}^{2+}}+2{{e}^{-}}\xrightarrow{{}}Fe\] is \[-0.44\]volt and\[{{E}^{o}}\] for \[Z{{n}^{2+}}+2{{e}^{-}}\xrightarrow{{}}Zn\]is \[-0.76\]volt thus:

    A)  \[Zn\] is more electropositive than \[Fe\]

    B)  \[Zn\] is more electronegative than \[Fe\]

    C)  \[Fe\] is more electropositive than \[Zn\]

    D)  none

    Correct Answer: A

    Solution :

                    High value for \[{{E}^{o}}_{red}\]. shows more electro negativity i.e., \[Zn\] is more electropositive than Fe. \[({{E}^{o}}_{Z{{n}^{2+}}/Zn}<{{E}^{o}}_{F{{e}^{2+}}/Fe})\]
