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. See Fig. 3-7.
Only CHâNHâ and CHâOH. Only CHâNHâ and CHâOH can have hydrogen bonds between other molecules of the same kind. To have hydrogen bonding, you need an N, O, or F atom in one molecule and an H attached to an N, O, or F atom in another molecule. See What is a Hydrogen bond? CHâF has an F atom, but no H-F bonds It cannot form hydrogen bonds with other CHâF molecules.
