Given `E_(Cl_(2)//Cl^(-))^(@)=1.36V,E_(Cr^(3+)//Cr)^(@)=-0.74V`
`E_("Cr_(2)O_(7)^(2-)//Cr^(3+))^(@)=1.33V,E_(MnO_(4)^(-)//Mn^(2+))^(@)=1.51V`
Among the following, the strongest reducing agent is

Options

A. `Cr`
B. `Mn^(2+)`
C. `Cr^(3+)`
D. `Cl^(-)`

Answer

A

Explanation

More negative the `E^(@)` value of the species , more stronger the reducing agent . Since `Cr^(3+)` is having least reducing potential , so Cr is the best reducing agent .
