In an octahedral complex, electrons in $d _ { z^2 }$ and $d _ { x ^ { 2 } - y ^ { 2 } }$ orbitals experience a greater repulsion from the lone pairs of electrons on ligands because these orbitals
A) contain more electrons than the other three d orbitals.
B) each contain one unpaired electron.
C) are oriented directly toward the incoming ligand electron pairs.
D) are located a greater distance from the metal ion nucleus.
E) are roughly spherical in shape, much like an s orbital.

Question

Quizplus · Accepted Answer

In an octahedral complex, the $d _ { z^2 }$ and $d _ { x ^ { 2 } - y ^ { 2 } }$ orbitals are oriented directly along the axes where the ligands approach, leading to greater repulsion from the ligand electron pairs.
