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

A

`[Fe(CN)_(6)]^(3-), [Co(CN)_(6)]^(3-)`

B

`CrO_(2)Cl_(2), MnO_(4)^(-)`

C

`TiO_(3),MnO_(2)`

D

`[Co(CN)_(6)]^(3-), MnO_(3)`

Text Solution

Verified by Experts

The correct Answer is:
B
The oxidation states of various metals :
(a) Fe=+3, Co=+3 (b) Cr=+6, Mn=+7
(c ) Ti=+6, Mn=+4 (d) Co=+3, Mn=+6
Thus we find that in (b) both Cr and Mn are in their highest oxidation states of +6 and +7 respectively.
