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
