The crystal field stabilization energy (...

The crystal field stabilization energy (CFSE) is the highest for

A

`[CoF_4]^(2-)`

B

`[Co(NCS)_4]^(2-)`

C

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

D

`[CoCl_4]^(2-)`

Text Solution

Verified by Experts

The correct Answer is:
C
Higher the oxidation states of the metal, greater the crystal field splitting energy. In options (a), (b) and (d), Co is present in +2 oxidation state and in (c) it is present in +3 oxidation state and hence has a higher value of CFSE.
