The π system (s) of the molecule are formed by the interaction of unhybridized p atomic orbitals on atoms employing sp 2 - and sp-hybridization.
WebJun 21, 2024 · Pi bonds are made by the overlap of two unhybridized p orbitals. Lone pair electrons are usually contained in hybrid orbitals. The hybrid orbitals used (and hence the hybridization) depends on how many electron groups are around the atom in question. An electron group can mean either a bonded atom or a lone pair.
