Which of the following is a set of reducing agents?

Options

A. `HNO_(3),Fe^(2+),F_(2)`
B. `F,Cl^(-),MnO_(4)^(-)`
C. `I^(-),Na,Fe^(2+)`
D. `CrO_(7)^(2-),CrO_(4)^(2-),Na`

Answer

C

Explanation

`2I^(-)rarrI_(2)+2e^(-)`
`NararrNa^(+)+e^(-)`
`Fe^(2+)rarrFe^(3+)+e^(-)`
As `I^(-)`, Na and `Fe^(2+)` can easily lose one or more electrons, they are all good reducing agents.
