In which of the following octahedral complexes of Co (at. no. 27), will the magnitude of `Delta_@` be the highest?

A

`[Co(CN)_6]^(3-)`

B

`[Co(C_2O_4)_3]^(3-)`

C

`[Co(H_2O)_6]^(3+)`

D

`[Co(NH_3)_6]^(3+)`

Text Solution

Verified by Experts

The correct Answer is:
A
CFSE (orystal field splitting energy) for octahedral complex, `Delta_@` depends on the strength of negative ligand.
