Question

In tetrahedral crystal field, three is splitting of d orbitals. Which of the following d orbitals constitute the higher energy set of orbirals.
A. `d_(xy), d_(x^(2)-y^(2))`
B. `d_(z^(2)), d_(x^(2)-y^(2))`
C. `d_(xy), d_(yz), d_(xz)`
D. `d_(z^(2)), d_(xz), d_(yz)`

Answer 1

Correct Answer - C
The second most common stereochemistry is tetrahedral. In the tetrahedral arrangement of four ligands around the metal ion, the `t_(2g)` orbitals `(d_(xy), d_(xz), d_(yz))` are more in line with the approaching ligands than the `e_(g)` orbitals `(d_(x^(2)-y^(2))` and `d_(z^(2)))` . As a result, it is the `(d_(x^(2)-y^(2))` and `d_(z^(2)))` orbitals that are lower in energy, and the tetrahedral energy diagram is inverted relative to the octahedral diagram.
