Question

CFSE for octahedral complexes with d8 configuration is_________.
A) -6Dq+4p
B)-12Dq+3p
C)-24Dq+3p

Answer 1

Answer:

C)-24Dq+3p

Explanation:

C)-24Dq+3p

Is the correct answer of this question.

CFSE for octahedral complexes with d8 configuration is -24Dq+3p .

The stability that occurs from putting a transition metal ion in the crystal field created by a collection of ligands is referred to as the crystal field stabilisation energy (CFSE).

The energy of the electron configuration in the ligand field minus the energy of the electronic configuration in the isotropic field is described as the Crystal Field Stabilization Energy. E=Eligand fieldEisotropic fieldCFSE=E=Eligand fieldEisotropic field

The stability that occurs from putting a transition metal ion in the crystal field created by a collection of ligands is referred to as the crystal field stabilisation energy (CFSE).

The value of CFSE is negative. When the splitting energy of the crystal field exceeds the pairing energy, electrons will first occupy all of the lower energy orbitals and then couple with electrons in these orbitals before proceeding.
