उत्तर

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.
