SUMMARY
The discussion centers on the energy levels of molecular orbitals, specifically the sigma 2p and pi 2p orbitals. It is established that the sigma 2p antibonding orbital is always higher in energy than the pi 2p antibonding orbital due to the mixing of sigma bonding p orbitals with sigma bonding s orbitals, which raises their energy. This energy shift occurs more significantly in bonding orbitals compared to antibonding orbitals, leading to a consistent ordering of these molecular orbitals across different diatomic molecules like C2, N2, and B2.
