Question

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

Answer 1

The molecular orbitals formed from 2s and 2p atomic orbitals are as follows:
$• Two\ molecular\ orbitals\ of\ 2s\ and\ σ ∗2s$
$• Six\ molecular\ orbitals\ of\ 2p: σ2pz, σ ∗2pz, π2px, π2py, π ∗2px, π ∗2py.$
Thus, the total number of molecular orbitals formed is 8.
