Question

What are the differences between ionic, covalent, and coordinate covalent bonds?

Answer 1

	Ionic Compound	Covalent Compound	Coordinate covalent bond
1.	Ionic compounds are crystalline solids at room temperature	It occurs in a gaseous state	It can exist as gases, liquids, or solids
2.	They are poor conductors of electricity in solid-state. However, in a molten state and their aqueous solutions conduct electricity.	They are bad conductors of electricity	Coordinate compounds also do not contain charged particles (ions), so they are bad conductors of electricity
3.	It has high melting and boiling point	Have a relatively low melting point	Have melting and boiling points higher than that of purely covalent compounds but lower than those of purely Ionic compounds
4.	Soluble in polar solvents and insoluble in a non-polar solvent	Soluble in non-polar solvents and insoluble in polar solvents	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.	They are neither hard nor brittle. But they are soft and waxy
