State differences between the properties of ionic compounds and covalent compounds.
|Ionic compounds||Covalent compounds|
|These contain electrovalent or ionic bond.||These contain covalent bond.|
|They are generally crystalline solids.||They are generally volatile liquids or gases.|
|They have high melting and boiling points.||They have low melting and boiling points.|
|They are bad conductors of electricity in solid state but are good conductors in the molten or aqueous states.||They do not conduct electricity.|
|They are generally soluble in water but insoluble in organic solvents.||They are generally soluble in organic solvents but insoluble in water.|
|They consist of ions. So, their reactions in solutions are fast.||They consist of molecules. So, their reactions in solutions are slow.|
