The crystal field splitting energy for octahedral`(Delta_(0))` and tetrahedral `(Delta_(t))` complexes is related as .

(a) `Delta_t=4/9Delta_o`

(b) `Delta_t=1/2Delta_o`

(d) `Delta_o=4/9Deltat`

Text Solution

Verified by Experts

The correct Answer is:

The crystal field splitting energy in case of tetrahedral complexes where only four ligands approach the central metal ion causing weak field around it is smaller than the crystal field splitting energy of octahedral complexes where six ligands approach the central metal ion and create a strong field around it. The two are related as `Delta_t=4/9Delta_0`.

The crystal field splitting energy for octahedral (Delta_(0)) and tetrahedral (Delta_(1)) complexes is related as

`Delta_(t)=-(1)/(2)Delta_(0)`

`Delta_(t)=-(4)/(9)Delta_(0)`

`Delta_(t)=-(3)/(5) Delta_(0)`

`Delta_(t)=-(2)/(5)Delta_(0)`

The crystal field splitting energy for octahedral complex (Delta_(0)) and that for tetrahedral complex (Delta_(t)) are related as:
