Hybridization and lone pairs

Postby 905022356 » Thu Nov 16, 2017 12:56 pm

Water has four regions of electron density, so it should have 4 sp^3 orbitals. Can oxygen's lone pairs of electrons occupy two sp^3 orbitals, or do they make oxygen have a different type of hybridization? Is there a different rule for hybridization of central atoms with lone pairs?

Each pair of electrons occupies one sp^3 orbital. There is no different rule for hybridization of central atoms with lone pairs; therefore, the oxygen in water has 4 sp^3 orbitals.

Lone pairs don't affect the hybridization of an atom. The number of election density regions does however so that's why H20 will have sp^3 hybridization regardless of its number of lone pairs.
