Question

The total number of molecular orbitals formed from 2s and 2p atomic orbitals of a diatomic molecule is _________.

Answer 1

The molecular orbitals derived from 2s and 2p atomic orbitals consist of:
\(• Two\ molecular\ orbitals\ of\ 2s:\ σ2s\ and\ σ ∗2s\)
\(• Six\ molecular\ orbitals\ of\ 2p:\ σ2pz, σ ∗2pz, π2px, π2py, π ∗2px, π ∗2py.\)
This results in a total of 8 molecular orbitals.
