HYDROGEN BONDING Meaning and
Definition
-
Hydrogen bonding is a type of intermolecular force that occurs when a hydrogen atom, covalently bonded to a highly electronegative atom, is attracted to another electronegative atom, creating a strong bond between them. In hydrogen bonding, the hydrogen atom acts as a bridge or a connector between two adjacent molecules or parts of the same molecule.
This phenomenon is primarily observed in interactions involving molecules containing hydrogen bonded to nitrogen (N), oxygen (O), or fluorine (F), which are known as the most electronegative elements. The highly electronegative atom is often referred to as the hydrogen bond donor, while the atom that accepts the hydrogen bond is called the hydrogen bond acceptor.
Hydrogen bonding has a significant impact on the physical and chemical properties of molecules and substances. It results in higher boiling points, melting points, and heat of vaporization for compounds compared to substances without hydrogen bonding. This is due to the extra energy required to break the strong intermolecular attractions in hydrogen bonding.
Moreover, hydrogen bonding plays a crucial role in various biological processes and structures. It contributes to the unique properties of water, such as its high specific heat capacity and the cohesive nature of liquid water. Hydrogen bonding also stabilizes protein structures, DNA double helix, and other biomolecules, influencing their structure, function, and overall stability.
Overall, hydrogen bonding is a fundamental concept in chemistry, explaining numerous phenomena and properties observed in both chemical and biological systems.

Etymology of HYDROGEN BONDING
The term "hydrogen bonding" was first introduced by the British chemist and physicist Latimer and Rodebush in 1920. It combines the word "hydrogen" with "bonding", indicating that it involves the interaction of hydrogen with other elements.
