$Mg$

Vedclass · Answer

(C) The tendency to undergo oxidation is determined by the standard oxidation potential of the metal. Metals with more negative standard reduction potentials (or more positive standard oxidation potentials) are more easily oxidized. Comparing the standard reduction potentials $(E^\circ_{red})$: $Mg^{2+} + 2e^- \rightarrow Mg$ $(E^\circ = -2.37 \ V)$ $Al^{3+} + 3e^- \rightarrow Al$ $(E^\circ = -1.66 \ V)$ $Zn^{2+} + 2e^- \rightarrow Zn$ $(E^\circ = -0.76 \ V)$ $Cu^{2+} + 2e^- \rightarrow Cu$ $(E^\circ = +0.34 \ V)$ Since $Mg$ has the most negative reduction potential,it has the highest tendency to lose electrons and undergo oxidation. Therefore,the correct option is $(C)$.
