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