In which of the following coordination entites the magnitude of `Delta_(0)` (CFSE in octehedral field) will be maximum.
`(At. No .Co = 27)`

A

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

B

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

C

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

D

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

Text Solution

Verified by Experts

The correct Answer is:
A
`CN^(-)` ion is a very strong field ligand and will cause maximum crystal field splitting . As a result , `delta_(o)` will be maximum.
