    \[{{E}^{o}}\] 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. \[({{E}^{o}}_{Z{{n}^{2+}}/Zn}<{{E}^{o}}_{F{{e}^{2+}}/Fe})\]
