Ø Ionic>Covalent>Hydrogen>VanderWaals Ionic bond is the strongest bond as they are formed by complete transfer of electrons. Covalent bond is weaker than the ionic bond as they are formed by the sharing of electrons. Hydrogen bond is weaker than ionic and covalent which are formed by the partial electrostatic attraction between a hydrogen atom which is bound to a more electronegative atom such as nitrogen, oxygen, fluorine and other adjacent atom bearing a lone pair of electron.
