Q.
$E^{{^\circ}}$ $for\ {Fe}^{2 +}\ + \ {2e}^{-}\ \rightarrow \ Fe$ is -0.44 V and $E^{{^\circ}}$ for
${Zn}^{2 +}\ + \ {2e}^{-}\ \rightarrow \ Zn$ is -0.76 V thus
A) Zn is more electropositive than Fe
B) Zn is more electronegative than Fe
C) Fe is more electropositive than Zn
D) None of the above
Explanation
(a)
High value for $E_{red}^{{^\circ}}$. Shows more electronegativity $i.e.,$ Zn is more electropositive than Fe. ($E_{{Zn}^{2 +}/Zn}^{{^\circ}} < \ E_{{Fe}^{2 +}\ /Fe}^{{^\circ}}$ )
