Study Notes
Chemical Bonding
Chemical bonding is the process by which atoms share or exchange electrons to form a chemical compound.
Types of Chemical Bonds
-
Ionic Bonds: Formed by the transfer of electrons between atoms, resulting in the formation of ions with opposite charges.
- Electronegative atoms (e.g. Cl, O) tend to gain electrons, becoming anions.
- Electropositive atoms (e.g. Na, Ca) tend to lose electrons, becoming cations.
-
Covalent Bonds: Formed by the sharing of electrons between atoms.
- Polar Covalent Bonds: Formed when electrons are shared unequally, resulting in a partial positive charge on one atom and a partial negative charge on the other.
- Nonpolar Covalent Bonds: Formed when electrons are shared equally, resulting in no net dipole moment.
- Hydrogen Bonds: A type of intermolecular force that arises from the attraction between a hydrogen atom bonded to a highly electronegative atom (e.g. O, N, F) and another electronegative atom.
Bonding Theories
- Valence Shell Electron Pair Repulsion (VSEPR) Theory: Predicts the shape of molecules based on the arrangement of electron pairs around the central atom.
- Molecular Orbital (MO) Theory: Describes the distribution of electrons in molecules in terms of molecular orbitals.
- Valence Bond (VB) Theory: Describes the formation of bonds in terms of the overlap of atomic orbitals.
Bond Properties
- Bond Length: The distance between the nuclei of two bonded atoms.
- Bond Angle: The angle formed by two bonded atoms and the central atom.
- Bond Order: The number of pairs of electrons shared between two atoms.
- Bond Polarity: The difference in electronegativity between two bonded atoms, affecting the distribution of electrons.
Molecular Shape and Polarity
- Molecular Shape: The arrangement of atoms in a molecule, influenced by VSEPR theory.
- Molecular Polarity: The overall polarity of a molecule, dependent on the polarity of individual bonds and the molecular shape.
