$\green{\bold{\underline{{ Properties \: of\: Ionic\: Compounds \: :}}}}$

1. They are in solid state and molecules are held Together by a strong forces so that they do not easily vaporise.

2. They have high melting and boiling points.

3. They do not conduct electricity in solid state but are good conductors in molten state or when dissolved in water.

4. They are soluble in water but insoluble in organic solvent.
