Select the correct order of oxidising power in acidic medium.

Options

A. `Cr_(2)O_(7)^(2-)gt MnO_(4)^(-)gtVO_(2)^(-)`
B. `MnO_(4)^(-)gtCr_(2)O_(7)^(2-)gtVO_(2)^(+)`
C. `VO_(2)^(+)gtMnO_(4)^(-)gtCr_(2)O_(7)^(2-)`
D. `MnO_(4)^(-)gtVO_(2)^(+)gtCr_(2)O_(7)^(2-)`

Answer

B

Explanation

Oxidising power depends upon the stability of reduction product obtained.
Since, lower oxides of Mn are more stable than that of Cr and V, so the order of oxidising power is `MnO_(4)^(-)gtCr_(2)O_(7)^(2-)gtVO_(2)^(-)`
