Answer : The correct option is, I & IV
Explanation :
Ionic compound : Ionic compound are the compounds which are made up of ions. These ions are held together by the electrostatic force of attraction between the oppositely charged ions.
Properties of ionic compounds :
- Ionic compounds are solid at room temperature.
- They have high boiling and melting point.
- They are highly soluble in water.
- They form crystalline structure because of strong electrostatic force of attraction between the oppositely charged ions.
Therefore, the option (I) and (IV) are the properties of ionic compounds.
