The CFSE for octahedral `[CoCl_(6)]^(4-)` is `18,000 cm^(-1)` . The CFSE for tetrahedral `[CoCl_(4)]^(2-)` will be

A

`18, 000 cm^(-1)`

B

`16,000 cm^(-1)`

C

`8,000 cm^(-1)`

D

`20, 000 cm^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
C
Thiosulfate `(S_2O_3)^(2-)` is a unidendate ligand and thus is not a chelating ligand.
