$d_{z^2}$

Vedclass · Answer

(B) The $d_{z^2}$ orbital has a unique shape with a major lobe along the $z$-axis and a ring of electron density in the $xy$-plane. Due to this geometry,it can participate in the formation of $\sigma$-bonds through head-on overlap along the $z$-axis. However,it cannot form $\pi$-bonds because its lobes do not have the required orientation for lateral overlap,and it cannot form $\delta$-bonds because it lacks the four-lobed structure required for face-to-face overlap.

Which of the following orbitals cannot form a $\pi$-bond as well as a $\delta$-bond?
