Based on spatial orientation, which of the following pairs of orbitals can successfully form a -bond — Chemical Bonding Chemistry Question

💡 Solution & Explanation

A $\pi$ -bond requires the interacting lobes to be perpendicular to the internuclear axis. A: $p_x$ is $\perp$ to y-axis $\rightarrow \pi$. B: $d_{xz}$ and $p_x$ lie in planes parallel to the z-axis $\rightarrow \pi$. C: $d_{yz}$ and $p_y$ lie in planes parallel to the z-axis $\rightarrow \pi$. D: $p_z$ along the z-axis forms a head-on $\sigma$ -bond.
