Hydrogen bond

Definition

A hydrogen bond is a type of weak chemical bond that forms when a hydrogen atom covalently bonded to one electronegative atom, such as oxygen or nitrogen, is attracted to another electronegative atom nearby. It plays a crucial role in determining the structure and properties of water and biological molecules like proteins and DNA.
