Question

The approach of ligand can break the degeneracy of d-orbitals. Select correct order of stability of different orbitals in square planar complex.

• A. $\left[\begin{array}{c}{d}_{yz}\\ d_{xz}\end{array}\right]>d_{z^2}>d_{xy}>d_{x^2-y^2}$
• B. $d_{x^2-y^2}>d_{xy}>d_{z^2}>d_{yz}>d_{xz}$
• C. $d_{x^2-y^2}>d_{xy}>d_{z^2}>\left[\begin{array}{c}{d}_{yz}\\ d_{xz}\end{array}\right]$
• D. $\left[\begin{array}{c}{d}_{xy}\\ d_{yz}\\ d_{xz}\end{array}\right]>\left[\begin{array}{c}{d}_{x^2-y^2}\\ d_{z^2}\end{array}\right]$

Answer 1

The correct option is A $\left[\begin{array}{c}{d}_{yz}\\ d_{xz}\end{array}\right]>d_{z^2}>d_{xy}>d_{x^2-y^2}$

Order of energy $d_{x^2-y^2}>d_{xy}>d_{z^2}>\left[\begin{array}{c}{d}_{yz}\\ d_{xz}\end{array}\right]$
