Which of the following arrangements represent increaseing oxidation nu

1.	Which of the following arrangements represent increaseing oxidation number of the central atom?A. `CrO_(2)^(-),CIO_(3)^(-),CrO_(4)^(-),MnO_(4)^(-)`B. `CIO_(3)^(-),CrO_(4)^(2-),MnO_(4)^(-),CrO_(2)^(-)`C. `CrO_(4)^(-),CIO_(3)^(-),MnO_(4)^(-),CrO_(4)^(2-)`D. `CrO_(4)^(2-),MnO_(4)^(-),CrO_(2)^(-),CIO_(3)^(-)`
Answer» Correct Answer - A The O.N of central atom in the different ions is: `CrO_(2)^(-):x-4=-1or x=+3` `CIO_(3):x-6=-1 or x=+5` `CrO_(4)^(2-): x-8=-2orx=+6` `MnO_(4)^(-):x-8=-1or x=+7` therefore is the correct increasing order.
