$d_{x^2-y^2}$ and $d_{z^2}$

Vedclass · Answer

(D) The $d$-subshell consists of five orbitals: $d_{x^2-y^2}, d_{z^2}, d_{xy}, d_{xz},$ and $d_{yz}$.In an octahedral coordination complex,the ligands approach along the $x, y,$ and $z$ axes.The orbitals $d_{x^2-y^2}$ and $d_{z^2}$ (collectively known as the $e_g$ set) have their electron density lobes directed along these axes,directly facing the incoming ligands.Conversely,the $d_{xy}, d_{xz},$ and $d_{yz}$ orbitals (the $t_{2g}$ set) have lobes oriented between the axes.Therefore,$d_{x^2-y^2}$ and $d_{z^2}$ are directly oriented towards the ligands.Hence,$(D)$ is the correct answer.
