Hydrogen bonding is the strongest type of intermolecular bond. It is a specific type of permanent dipole to permanent dipole attraction that occurs when a hydrogen atom is covalently...
Sep 27, 2024 · hydrogen bonding, interaction involving a hydrogen atom located between a pair of other atoms having a high affinity for electrons; such a bond is weaker than an ionic bond or covalent bond but stronger than van der Waals forces.

Jan 30, 2023 · A hydrogen bond is an intermolecular force (IMF) that forms a special type of dipole-dipole attraction when a hydrogen atom bonded to a strongly electronegative atom exists in the vicinity of another electronegative atom with a lone pair of electrons.
In chemistry, a hydrogen bond (or H-bond) is primarily an electrostatic force of attraction between a hydrogen (H) atom which is covalently bonded to a more electronegative "donor" atom or group (Dn), and another electronegative atom bearing a lone pair of electrons—the hydrogen bond acceptor (Ac).

A hydrogen bond is a type of attractive (dipole-dipole) interaction between an electronegative atom and a hydrogen atom bonded to another electronegative atom. This bond always involves a hydrogen atom. Hydrogen bonds can occur between moleculesor within parts of a single molecule. A hydrogen bond tends to be stronger than van der Waals forces, but...
How can hydrogen be attracted to another atom when it is already bonded? In a polar bond, one side of the bond still exerts a slight positive charge, while the other side has a slight negative electrical charge. Forming a bond doesn't neutralize the electrical nature of the participant atoms.
Hydrogen bonds are found in nucleic acids between base pairs and between water molecules. Hydrogen bonds also form between hydrogen and carbon atoms of different chloroform molecules, between hydrogen and nitrogen atoms of neighboring ammonia molecules, between repeating subunits in the polymer nylon, and between hydrogen and oxygen in acetylaceton...
Although hydrogen bonds form between hydrogen and any other electronegative atom, the bonds within water are the most ubiquitous (and some would argue, the most important). Hydrogen bonds form between neighboring water molecules when the hydrogen of one atom comes between the oxygen atoms of its own molecule and that of its neighbor. This happens b...
