1.	The pair of compounds having metals in their highest oxidation state is .A. `MnO_(2),FeCI_(3)`B. `[MnO_(4)]^(Θ),CrO_(2)CI_(2)`C. `[Fe(CN)_(6)]^(3-),[Co(CN)_(6)]^(3-)`D. `[NiCI_(4)]^(2-),[CoCI_(4)]^(Θ)`
Answer» Correct Answer - b `MnO_(2)(+4)` and `FeCI_(3)(+3)` (b) `MnO_(4)^(Θ)(+7)` and `CrCO_(2)CI_(2)(+6)` (c ) `[Fe(CN)_(6)]^(3-)(+3)` and `[Co(CN)_(6)]^(3-) (+3)` (d) `[NiCI_(4)]^(2-)` and `[CoCI_(4)]^(+3)` For manganese, `+7` is the maximum oxidation state and for chromium `+6` is the maxium oxidation state .
