ionic bonds have high emelting point amf boiling point while covale t bonds have low melting point and boiling point.
ionic bonds cannot conduct electricity in solid state but can conduct in the molten state or when dissolves in water. while covalent bonds cannot conduct electricity in any state.
ionic bonds are soluble in water but insoluble in organic solvents while most covalent bonds are soluble in organic solvents but insoluble in water
