Ionic compounds are those compounds which are formed by the transfer of electrons from a metal to a non-metal. For example, NaCl
Properties:
(i) Physical nature: Ionic compounds are hard and solid due to strong force of attraction between oppositely charged ions.
(ii) Melting point and boiling point: A more amount of energy is required to break strong bonds. So, they have high melting point and boiling point.
(iii) Solubility: These are soluble in water (polar solvent) but insoluble in organic solvent.
(iv) Conduction of electricity: They conduct electricity in solution or molten state as ions move towards opposite electrodes.
