Molecular Orbitals : combine atomic orbitals (AOs) from all the atoms in a molecule into the same number of molecular orbitals. MOs have different shapes, sizes, and energies, and have two electrons max. per orbital (Pauli Exclusion Principle).By stewart-velazquez

COVALENT BONDING: ORBITALS. HYBRIDIZATION (9.1). HYBRIDIZATION. Consider methane,CH 4 C has 4 valence electrons 1s 2 2s 2 2p 2
Chapter 9. Covalent Bonding: Orbitals. Types of bonds. Sigma bonds Overlap of orbitals from two atoms Between the atoms Pi bonds Above and below atoms Between p orbitals Second bond of all double bonds. Hybridization and Electrons.
Covalent Bonding: Orbitals. Chapter 09. The four bonds around C are of equal length and Energy. Can you explain this based on your knowledge of electron energy levels?. 6 C 1s 2 2s 2 2p 2. Bonding from s is Different from bonding From p. In addition the Angles should be within
Covalent Bonding: Orbitals. 9.1 Hybridization and the localized electron model. Remember that the localized electron model says that molecules are a collection of atoms bound by sharing electrons and represented by Lewis structures.
Covalent Bonding: Orbitals. Hybridization – mixing of two or more atomic orbitals to form a new set of hybrid orbitals. Mix at least 2 nonequivalent atomic orbitals ( e.g. s and p). Hybrid orbitals have very different shape from original atomic orbitals.
8.3. Molecular Orbitals. Molecular Orbitals How are atomic and molecular orbitals related?. 8.3. Molecular Orbitals. When two atoms combine, the molecular orbital model assumes that their atomic orbitals overlap to produce molecular orbitals , or orbitals that apply to the entire molecule.
Two interacting orbitals make two new orbitals . Using a 1s orbital on two H atoms:. Molecular Orbitals. anitbonding orbital = higher energy. bonding orbital = lower energy. Atomic orbitals on the sides; molecular orbitals inside. MO Diagrams: H and He molecules.
