Based On The MO Diagram, Is Ethyne More Likely To Act As A Lewis Acid, Base, Or Neither? Its chemistry is dominated by two "frontier orbitals", that is the Highest Occupied Molecular Orbital (HOMO) and the Lowest Unoccupied Molecular Orbital (LUMO). As each hydrogen bonds, an sp 3 orbital of the carbon mixes with a hydrogen 1s orbital to create a bonding molecular orbital (BMO) and an anti-bonding orbital (ABMO). (McQuarrie & Simon, Physical Chemistry: A Molecular Approach, p. ) Methane has eight valence electrons, so according to the aufbau and Pauli exclusion principles the two. Explore bonding orbitals in other small molecules. The unbonded energy levels are higher than those of the bound molecule, which is the energetically-favored configuration. Consider an ethyne molecule (CH = CH). The four p atomic orbitals form two π and two π* molecular orbitals. In ethyne molecule, each carbon atom is Sp-hybridized.
