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

A

18000 `cm^(-1)`

B

16000 `cm^(-1)`

C

8000 `cm^(-1)`

D

2000 `cm^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
D
`Delta_(t)=(4)/(9)Delta_(0)`
`thereforeDelta_(t)` for `[CoCl_(4)]^(2-)=(4)/(9)xx18000cm^(-1)=8000cm^(-1)`
