The d_z²and d_x² - _y² orbitals are higher in energy than the d_xy, d_xz, and d_yz orbitals in an octahedral complex because these two orbitals ________ A)do not point directly at ligands. B)point directly at ligands. C)occupy larger volumes than the other three orbitals. D)are in the same plane and repel one another. E)occupy smaller volumes than the other three orbitals.

Question

Quizplus · Accepted Answer

In an octahedral complex, the d orbitals split into two sets due to the ligand field. The d_z^2 and d_x^2-y^2 orbitals (referred to in the question) are higher in energy because they point directly at the ligands, leading to greater repulsion and higher energy levels compared to the d_xy, d_xz, and d_yz orbitals, which are oriented between the ligands.
