hydrogen bonding

Hydrogen bonding is a type of attraction that occurs when a hydrogen atom, which is covalently bonded to a more electronegative atom like oxygen or nitrogen, interacts with another electronegative atom. This bond is weaker than a covalent bond but plays a crucial role in the behavior of water, influencing its boiling and melting points. Hydrogen bonding also helps determine the structure of proteins and DNA, contributing to life’s complexity. Essentially, it's a key force that influences how molecules interact and maintain their structure in various biological and chemical processes.
