Detailed explanation-1: -Answer and Explanation: An example of a hydrogen bond is the attraction between the hydrogen (H) of a water molecule and the oxygen (O) of another water molecule.
Detailed explanation-2: -Cohesion: Hydrogen Bonds Make Water Sticky In the case of water, hydrogen bonds form between neighboring hydrogen and oxygen atoms of adjacent water molecules. The attraction between individual water molecules creates a bond known as a hydrogen bond.
Detailed explanation-3: -In chemistry, a hydrogen bond (or H-bond) is a primarily electrostatic force of attraction between a hydrogen (H) atom which is covalently bound to a more electronegative “donor” atom or group (Dn), and another electronegative atom bearing a lone pair of electrons-the hydrogen bond acceptor (Ac).
