The pair of compounds in which metals are in the highest possible oxidation state is

A$$ \left[ Fe(CN)_{ 6 } \right] ^{ 4- },\ \left[ Co(CN)_{ 6 } \right] ^{3-} $$
B$$CrO_2Cl_2,MnO^-_4 $$
Correct Answer
C$$TlO_2,\ MnO_2 $$
D$$ \left[ Co(CN)_{ 6 } \right] ^{3-},\ MnO_3 $$

Solution

$$\overset { +6 } { CrO }_{ 2 }{ Cl }_{ 2 } $$ and $$\overset { +7 }{ { MnO }_{ 4 } } $$ is the pair of compounds in which metals are in the highest possible oxidation state.
