The vlaue for crystal field stabilisation energy for an octahedral comlex, `[CoCI_(6)]^(4-)` is 18000 `cm^(-1)` The value of crystal field stabilisation energy for tetrahedral complex is

Options

A. `16000 cm^(-1)`
B. `8000 cm^(-1)`
C. `20000 cm^(-1)`
D. `18000 cm^(-1)`

Explanation

(b) The CFSE for terrahedral complex is `(4)/(9)Delta_(0)` where `Delta_(0)` is CFSE for ocatahedral complexes. The value of `Delta_(0)` is `18000 cm^(-1)` "therefore" , the CFSE for terahedral complex is `(4)/(9) ` of `18000 cm^(-1)` that is `8000 cm^(-1)`
