General Properties:
* Low melting and boiling points: Compared to ionic compounds, covalent compounds generally have weaker intermolecular forces (forces between molecules), leading to lower melting and boiling points.
* Poor electrical conductivity: Covalent compounds are generally poor conductors of electricity in both solid and liquid states because they lack free-moving charged particles (ions).
* Solubility in non-polar solvents: Covalent compounds, especially those with non-polar bonds, tend to dissolve in non-polar solvents like hydrocarbons.
* Often exist as gases or liquids at room temperature: Due to their weaker intermolecular forces, many covalent compounds are gases or liquids at room temperature.
Specific Properties:
* Strong intramolecular bonds: Covalent compounds have strong bonds within the molecule (covalent bonds), but weaker intermolecular forces between molecules.
* Variable melting and boiling points: While generally lower, the melting and boiling points can vary widely depending on the size and complexity of the molecules.
* Can be solids, liquids, or gases: The physical state at room temperature depends on the strength of intermolecular forces.
* Can be flammable: Some covalent compounds are highly flammable, especially those containing carbon and hydrogen (hydrocarbons).
* Variable reactivity: The reactivity of covalent compounds depends on the specific elements involved and the types of bonds present.
Examples:
* Water (H₂O): A liquid at room temperature, good solvent for polar molecules, but a poor conductor of electricity.
* Methane (CH₄): A gas at room temperature, flammable, non-polar, and soluble in non-polar solvents.
* Sugar (C₁₂H₂₂O₁₁): A solid at room temperature, soluble in water, non-conductor of electricity.
