Hello, The geometric form of the water molecule is explained in chemistry books by the hybridization of certain orbitals, in this case the 2p and 2s orbitals.The resulting hybridized orbital then gets the geometric form observed. I know that hybridization is permitted by the fact that Shrodinger's equation is linear.But what I don't understand is "when" orbitals hybridize and when don't they? Do orbitals in isolated atoms hybridize ?Or is hybridization a phenomenon only occuring when two or more atoms approach eachother? I personnaly understand by hybridization the interference of the wave functions of two or more electrons.Is this correct? Thank you very much.
