Title: [Chemistry] Hybridization problem
Post by: Mr. Despair on December 29, 2009, 03:58:49 pm

why the hybridization of CO is sp?
shouldn't only sigma bonds be formed by hybridized orbitals?

i think ur rite about sigma bonds being formed by hybridized orbitals.
CO has three covalent bonds so it has 2 pi bonds and 1 sigma bond.
sp- means a hybridized orbital which looks halfway between and s and p orbital

so does this mean that hybridized orbital can also be used to form pi bonds?

no i dont think hybridized orbitals form pi bonds. They only form sigma bonds. It is just that some p orbitals are not hybridized.
