If for the complex K_(4)[FeL_(6)] the value of Delta_(0)=22000" "cm^(-1). Find out the value of crystal pairing energy. Where L is uninegative monodentate ligand.
Answer» `-46200" "cm^(-1)` `-52800" "cm^(-1)` `+2200" "cm^(-1)` `-22200" "cm^(-1)` SOLUTION :`K_(4)[overset(+2)FeL_(6)] d^(6) to t_(2g)^(2,2,2)EG^(0,0)` CFSE`=-0.4xx6Delta_(0)=-2.4Delta_(0)` `implies "CFSE"=-2.4xx22000=-52800 cm^(-1)`
