Which of the following overlapping combinations is correctly matched with the type of coordinate bac — Chemical Bonding Chemistry Question

💡 Solution & Explanation

A $p\pi-d\pi$ bond requires lateral overlap between a $p$ -orbital and a $d$ -orbital. If the internuclear axis is the x-axis, the $p_y$ orbital and $d_{xy}$ orbital lie in parallel planes and their respective lobes can overlap laterally to form a $\pi$ -bond. The $d_{z^2}$ orbital typically forms $\sigma$ bonds, and $s$ -orbitals cannot form $\pi$ bonds.
