Question

List two differences between the properties exhibited by covalent compounds and ionic compounds.

List down the differences between Ionic and Covalent compounds.

Answer 1

Sr. No.	Ionic Compound	Covalent Compound
1.	Ionic compounds are crystalline solids at room temperature.	It occurs in a gaseous state.
2.	They are poor conductors of electricity in a solid state. However, in a molten state and their aqueous solutions conduct electricity.	They are bad conductors of electricity.
3.	It has high melting and boiling points.	Have relatively low melting points.
4.	Soluble in polar solvents and insoluble in a non-polar solvent.	Soluble in non-polar solvents and insoluble in polar solvents.
5.	They have high density and they are quite hard because of the strong electrostatic force between the ions. But they are highly brittle.	They are neither hard nor brittle. But they are soft and waxy.
6.	Undergoes ionic reactions which are practically rapid and instantaneous.	Undergo molecular reactions in solutions and these reactions are slow.
