Which of the following is most easily oxidised ?

A

`[Co(CN)_(6)]^(4-)`

B

`[Co(NO_(2))_(6)]^(3-)`

C

`[Co(NH_(3))_(6)]^(2+)`

D

`[Co(en)_(3)]^(2+)`

Text Solution

Verified by Experts

The correct Answer is:
A
`[Co(CN)_(6)]^(4-):Co^(2+):3d^(7)`

`overset(Ө)CN` is strong field ligand among all given ligands hence `[Co(CN)_(6)]^(4-)` is easily oxidised into `[Co(CN)_(6)]^(3-)`.
