In MnO 4-, Mn 7+ is in highest oxidation state possible for Mn. In CrO 2 Cl 2, Cr 6+ is in highest oxidation state possible for Cr.

Q. The pair of compounds having metals in their highest oxidation state is

$M n O_{2}, F e C l_{3}$

$[M n O_{4}]^{-}, C r O_{2} C l_{2}$

$[F e (CN)_{6}]^{3 -}, [C o (CN)_{3}]$

$[N i C l_{4}]^{2 -}, [C o C l_{4}]^{-}$

In $M n O_{4}^{-}, M n^{7 +}$ is in highest oxidation state possible for $M n$ . In $C r O_{2} C l_{2}, C r^{6 +}$ is in highest oxidation state possible for $C r$ .
