Question

Which of the following are true about the energy of the given d-orbitals of a tetrahedral complex ?

A. $d_{xy} = d_{xz} > d_{x^{2} - y^{2}}$

B. $d_{xy} = d_{yz} > d_{z^{2}}$

C. $d_{x^{2} - y^{2}} > d_{z^{2}} > d_{xz}$

D. $d_{x^{2} - y^{2}} = d_{z^{2}} < d_{xz}$

Choose the correct answer from the options given below :

Options

A.A, B and D only
B.A and B only
C.B and D only
D.B, C and D only

Solution

Sol. [Key Concept: For a tetrahedral complex the $e$ set ($d_{x^{2} - y^{2}},d_{z^{2}}$) lies below the $t_{2}$ set ($d_{xy},d_{yz},d_{zx}$); statements A, B and D follow.]

Order of energy in tetrahedral splitting $(dxy = dyz = dzx) < d_{x^{2} - y^{2}} = d_{z^{2}}$

$A,B$ and D are correct.
