(a)
Interpretation:
The bonding and antibonding MOs that would result from the end-on overlap of chlorine AOs in the
Concept introduction:
Overlap of orbitals will result in a bonding MO if their phases in the overlapping parts are the same. In this case, the electron density increases between the nuclei of the two atoms.
The overlap will result in an antibonding MO if their phases are opposite in the overlapping parts. In this case, the electron density between the nuclei of the atoms reduces.
(b)
Interpretation:
The symmetry of the MOs resulting from the overlap of AOs in the
Concept introduction:
Symmetry of an MO depends on whether the overlap is end-on- or sideways. End-on overlap is called
