Study Notes
Overview of Chemical Bonding Theories
Chemical bonding theories explain how atoms share or exchange electrons to form chemical bonds.
Valence Shell Electron Pair Repulsion (VSEPR) Theory
- Predicts the shape of molecules based on the arrangement of electron pairs around the central atom
- Electron pairs (bonding and non-bonding) repel each other, resulting in a specific molecular shape
- Used to predict molecular geometry and polarity
Valence Bond (VB) Theory
- Describes the formation of a covalent bond as the overlap of atomic orbitals
- Atomic orbitals hybridize to form hybrid orbitals, which then overlap to form bonds
- Explains the directionality of bonds and the shape of molecules
Molecular Orbital (MO) Theory
- Describes the delocalization of electrons within a molecule
- Molecular orbitals are formed by the combination of atomic orbitals
- MO theory explains the magnetic and spectroscopic properties of molecules
Electrostatic Attraction Theory
- Describes the attraction between positively charged nuclei and negatively charged electrons
- The electrostatic attraction between opposite charges holds atoms together in a molecule
- Explains the formation of ionic bonds
Lewis Theory
- Describes the formation of covalent bonds as the sharing of electrons
- Atoms share electrons to achieve a full outer energy level (octet)
- Introduces the concept of electron pair bonds and lone pairs
Molecular Orbital Diagrams
- A visual representation of the molecular orbitals in a molecule
- Shows the energy levels and arrangement of electrons within a molecule
- Helps to explain molecular properties and reactivity
