Direction (Q. Nos. 16 and 17) This section contains a paragraph, describing theory, experiments, data, etc. Two questions related to the paragraph have.
Passage
In octahedral complexes due to repulsion between the ligands and d-orbitals, there is splitting of d-orbitals into two sets, i.e. two orbitals of higher energy called eg and three orbitals of lower energy called t2g. The difference of energy between the two sets of d-orbitals is called crystal field stabilisation energy denoted by Δo. For any given metal cation, the magnitude of Δo depends on the nature of ligands.
Q. 
The CFSE for d7 configuration for strong ligand field is
  • a)
    -1.6 Δo 
  • b)
    -2.0 Δo 
  • c)
    -2.4 Δo 
  • d)
    -1.8 Δo

The total crystal field stabilisation energy is given by CFSE(octahedral) = are the number of electron occupying the t2g and eg orbitatls respectively.
For d7 in strong field,

CFSE = -0.4 x 6 + 0.6 x 1 = -2.4 + 0.6 = -1.8Δo

CFSE for d7 configuration in octahedral complexes with strong ligand field is -1.8 o.

Explanation:

CFSE (Crystal Field Stabilization Energy) is the energy difference between the two sets of d-orbitals (eg and t2g) in octahedral complexes. The magnitude of CFSE depends on the nature of ligands.

In octahedral complexes, the d-orbitals split into two sets due to repulsion between the ligands and d-orbitals. The eg set consists of two orbitals of higher energy, while the t2g set consists of three orbitals of lower energy.

For a d7 configuration, there are 7 electrons in the d-orbitals. In a strong ligand field, the electrons will preferentially occupy the lower energy t2g orbitals due to the strong interaction with the ligands. This leads to a lower energy state, resulting in a negative CFSE.

The magnitude of CFSE for a d7 configuration in a strong ligand field is -1.8 o. This value indicates the stabilization energy gained by the system due to the splitting of d-orbitals and the arrangement of electrons in the t2g set.

The negative value of CFSE indicates that the energy of the system is lowered due to the interaction between the ligands and the d-orbitals. This stabilization energy is a result of the electrostatic interactions between the ligands and the metal cation.

In summary, the CFSE for a d7 configuration in octahedral complexes with a strong ligand field is -1.8 o. This negative value signifies the lowering of energy and stabilization of the system due to the splitting of d-orbitals and the arrangement of electrons in the t2g set.
