Identify the correct statements regarding the Molecular Orbital Theory (MOT) of diatomic molecules. — Chemical Bonding Chemistry Question

💡 Solution & Explanation

Statement D is incorrect: due to significant $s-p$ orbital mixing in molecules like $B_2$, $C_2$, and $N_2$ (where $\le 14 e^-$), the $\sigma 2p_z$ orbital is pushed to a higher energy level than the $\pi 2p_x$ and $\pi 2p_y$ orbitals. Statements A, B, and C accurately reflect the MOT configurations of those respective species.
