In which of the following coordination entities the magnitude of `Delta_(0)` (CFSE in octahedral field) wiil be maximum? (At. no. of Co = 27)

A

`[CoH_(2)O)_(6)]^(3+)`

B

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

C

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

D

`[Co(C_(2)O_(4))_(3)]^(3-)`

Text Solution

Verified by Experts

The correct Answer is:
C
As `CN^(-)` is the stronger ligand among the given option hence the magnitude of `Delta_(0)` will be maximum in `[Co(CN)_(3)]^(3-)`.
