Answer» There are several conditions for the linear combination of atomic orbitals. Among these, the most important two are: The participating orbitals must have same or nearly same energy. For example, 1s orbital of one atom cannot combine with 2s orbital of another atom. The corresponding orbitals of both atoms should have the same symmetric orientation around the molecular axis. Although all the three orbitals of 2p have the same energy, 2pz orbital of one atom can only combine with the 2pz orbital, not 2px or 2py, of the other atom. When two atomic orbitals with the same energy and orientation overlap considerably, the new molecular orbitals are generated from the linear combination of the atomic orbitals. please like answerif you find it useful |
