WebA hydrogen bond is a type of chemical bond that involves the electrostatic attraction between a hydrogen atom and an atom containing a lone pair of electrons in a substance. In order for a hydrogen bond to occur, the hydrogen must be bonded to an electronegative atom. The hydrogen bond is not covalent, although the molecules present in the ... WebThese are the strongest bonds between atoms which can be further divided as follows: (i) Ionic (or electrostatic) bond. (ii) Covalent (or atomic or homopolar) bond. (iii) Metallic bond. 2. Secondary (or Molecular) Bonds: Attraction forces (also called ven der Waals forces) exist between atoms or molecules. These bonds are weaker than primary bonds.
