- 3.1: Bonding in compounds
- Covalent and ionic bonds that hold atoms together in molecules are described. Representing a compound by formula and properties of the compounds are also introduced.
- 3.2: Naming binary ionic compounds
- Naming cations, anions, and binary ionic compounds are described. Writing the formulae from the names of the ionic compounds is also described.
- 3.3: Polyatomic ions and their compounds
- Polyatomic ions, their nomenclature, the name of the compounds containing polyatomic ions, and the writing formulae of these compounds from their names are described.
- 3.4: Naming acids
- The nomenclature of acids that do not contain oxyanions and those containing oxyanions is described.
- 3.5: Naming binary covalent compounds
- Nomenclature of binary covalent compounds, i.e., writing names from formulae and writing formulae from the names are described.
- 3.6: Lewis structures of molecules
- A systematic procedure for writing Lewis structures of compounds and exceptions to the octet rule are discribed.
- 3.7: Molecular shapes –Valence shell electron pair repulsion (VSEPR) theory
- The 3D shapes of molecules are explained on the basis of valence shell electron pair repulsion theory.
- 3.8: Polarity of molecules
- The polarity of molecules based on polar bonds and vector addition of the polarity vectors of the bonds in a molecule are described.
- 3.9: Intramolecular forces and intermolecular forces
- Intramolecular forces, i.e., ionic, covalent, and metallic bonds, and intermolecular forces based on electrostatic interactions between permanent or transient dipoles, and hydrogen bonding are described.
