Chemistry

The document discusses the differences between ionic and covalent compounds, highlighting their distinct properties. Ionic compounds are characterized by their ability to conduct electricity when molten or dissolved in water, but not in their solid state.

Compounds

Ionic Compounds

High melting and boiling point
Souluble in water but not in organic solvent
Can conduct electricity in molten and aqueous state but not in solid state.
Non-volatile

Covalent Compounds

Covalent molecules have low melting and boiling point because of weak intermolecular forces. Therefore little heat is neede to overcome these forces.
Properties
Volatile
Usually are gases or liquid at room temperature.
Low melting and boiling point.
Soluble in organic solvent but insoluble in water.
Cannot conduct electricity in any form
