WebMay 14, 2024 · Hydrogen bonds can form whenever a strongly electronegative atom (e.g., oxygen, nitrogen) approaches a hydrogen atom which is covalently attached to a second strongly-electronegative atom Some common examples: between the −C=O group and the H-N− group of nearby peptide bonds in proteins giving rise to the alpha helix and beta … WebHydrogen bonding in water is often the most common example of these bonds due to their importance in many properties of water. In water, the hydrogen bond occurs between the oxygen of one molecule and the hydrogen of another.
