Chemical Bonding
- A chemical bond is the attractive force between atoms or molecules that enables them to combine and form compounds.
- Chemical bonds are categorized by the process responsible for their formation, including the sharing or transfer of electrons.
- Strong chemical bonds result from the sharing or transfer of electrons, whereas weak interactions include hydrogen bonds and van der Waals forces.
- Chemical bonding occurs due to a decrease in potential energy as atoms approach each other.
- The forces of attraction and repulsion between atoms, including nuclei and electrons, determine whether a bond will form.
- The noble gases are inert because they have stable electron configurations.
- Lewis symbols and octet rule explain the valence electrons crucial for bonding.
- Ionic bonds are formed through electron transfer, creating oppositely charged ions that attract electrostatically.
- Covalent bonds form when atoms share electrons to achieve stable electron configurations.
- Covalent bonding occurs through sharing of electrons (single, double, or triple bonds) to satisfy the octet rule.
- Dipole moments describe the polarity in a covalent bond, arising from unequal electron sharing.
- Intermolecular forces, including dipole-dipole interactions, dipole-induced dipole interactions, London dispersion forces, and hydrogen bonding, influence the physical properties of substances.
- Hydrogen bonding is a specific type of intermolecular force between a hydrogen atom covalently bonded to a highly electronegative atom and another highly electronegative atom in a different molecule.
- The strength of intermolecular forces affects the boiling and melting points, solubility, and other properties of substances.
- Resonance and hybrid structures can represent molecules with delocalized electrons.
- Hybridisation results in new atomic orbitals from a combination of other atomic orbitals. This explains the geometries of molecules containing lone pairs of electrons and multiple bonds.
