The correct order of oxidizing nature of `Ocl^(-), Obr^(-)` and `Ol^(-)` ions are............

Options

A. `Ocl^(-) gt Obr^(-) gt Ol^(-)`
B. `Ol^(-) gt Ocl^(-) gt Obr^(-)`
C. `Ol^(-) gt Obr^(-) gt Ocl^(-)`
D. `Obr^(-) gt Ocl^(-) gt Ol^(-)`

Answer

A

Explanation

This can be explained on the basis of standard electrode potentials. The standard electrode potentials of `Ocl^(-), Obr^(-)` and `Ol^(-)` are 1.61 V, 1.60 V and 1.44 V respectively.
