  The MCAS Way extends the MCAS concept of atomic orbitals to molecular
bonding. There are many examples given for each bonding type. Part I: The MCAS
atomic orbital concept. There are no spherical orbitals and spin pairing does
not occur through spin reversal. Quantum numbers do not validate coexistence in
identical space. Part II: Single bonds. There are no sigma-bonds wherein two
electrons occupy identical space on a line between nuclei; only off-axis (Xi)
bonding. Covalent bonding is purely electrostatic; just like ionic bonding.
Part III: Triple bonds. There are no Pi-bonds in a triple bond. Part IV: Simple
double bonds. There are no sigma bonds; only Pi| and Pi_ bonds. Part V:
Multiple bonds. The traditional Pi-cloud is only a group of reciprocating,
vertically pumping, electron pistons. Electrons conjugate by flowing around
nuclei in the nuclear plane. Atoms adopt a twelve-lobed (T12) orbital
arrangement for multiple bonding. Aromaticity is defined by 2(2n+1), not
(4n+2). Part VI: Miscellaneous compounds. Isoelectronic XO3, phosphorous and
its oxides, and boranes.
