Which of the following increasing order of oxidising power is correct for the following species?
`VO_(2)^(+),MnO_(4)^(-),Cr_(2)O_(7)^(2-)`

Options

A. `VO_(2)^(+)ltCr_(2)O_(7)^(2-)lt MnO_(4)^(-)`
B. `VO_(2)^(+)ltMnO_(4)^(-)ltCr_(2)O_(7)^(2-)`
C. `Cr_(2)O_(7)^(2-) lt VO_(2)^(+)ltMnO_(4)^(-)`
D. `Cr_(2)O_(7)^(2-)ltMnO_(4)^(-)ltVO_(2)^(+)`

Explanation

To determine the increasing order of oxidizing power for the species \( VO_2^+, MnO_4^-, \) and \( Cr_2O_7^{2-} \), we need to analyze the stability of the reduced forms of these species. The more stable the reduced form, the greater the oxidizing power of the original species.

### Step-by-Step Solution:

1. **Identify the Reduced Forms**:
- \( VO_2^+ \) gets reduced to \( V^{3+} \).
- \( MnO_4^- \) gets reduced to \( Mn^{2+} \).
- \( Cr_2O_7^{2-} \) gets reduced to \( Cr^{3+} \).
