Hybridization and Sigma and Pi bonds

  • #1

Main Question or Discussion Point

Say we have sp2 hybridization of nitrogen, can the unhybridized p orbital form sigma bonds too or can it only form pi bonds? So in the case of nitrogen, it would be able to form molecules with 2 sigma bonds and one pi bond, correct?
Thanks

Correct, I think - isn't this just what we have in e.g. oximes, or imines?

It makes no sense to speak of an sp2 hybridized nitrogen atom as something different from e.g. an sp3 hybridized nitrogen or an un-hybridized nitrogen. The concept of hybridization makes sense only in valence bond theory, and even there it is only seldomly necessary.
E.g. the bonds in a molecule like NH3 can equally well be described in terms of sp3 hybrid orbitals or un-hybridized p orbitals.
