Standard potentials (E°) for some half-reactions are given below:
`Sn^(4+) + 2e rightarrow Sn^(2+) , E^(@) = + 0.15V`
`2Hg^(2+) + 2e rightarrow Hg_(2)^(2+) , E^(@) = 0.92 V`
`pbo_(2) + 4H^(+) + 2e rightarrow pb^(2+)+ 2H_(2)O , E^(@) = + 1.45 V`
Based on the above , Which one of the following statement is correct?

Options

A. `Sn^(4+)` is a stronger oxidising agent than `Pb^(4+)`.
B. `Sn^(2+)` is a stronger reducing agnet than `Hg_(2)^(2+)`.
C. `Hg^(2+)` is a stronger oxidising agent than `Pb^(4+)`.
D. `Pb^(2+)` is a stronger reducing agnet than `Sn^(2+)`.

Answer

D
