Hydrogen bonds (H-bonds) are a specific type of electrostatic interaction between a proton attached to an electronegative atom (such as N or O) and a lone pair of electrons on an electronegative atom such as N, O, or F. The former is called the H-bond donor, the latter the H-bond ...
What Is a Hydrogen Bond? Hydrogen bonds are not “true” bonds like covalent and ionic bonds, but rather directional electrostatic attractions between slightly negative and slightly positive atoms. The standard configuration of a hydrogen bond is of the type D— H···A where: H is a hydrogen...
The meaning of HYDROGEN BOND is an electrostatic attraction between a hydrogen atom in one polar molecule (as of water) and a small electronegative atom (as of oxygen, nitrogen, or fluorine) in usually another molecule of the same or a different polar su

What is a hydrogen bond? How do they work? Would you describe those bonds as strong or weak?Types of Bonds:There are many types of bonds that exist between two atoms. The stronger the bond between them, the stable the molecule will be. The type of bond ...

(Chemistry) a weak chemical bond between an electronegative atom, such as fluorine, oxygen, or nitrogen, and a hydrogen atom bound to another electronegative atom. Hydrogen bonds are responsible for the properties of water and many biological molecules ...
Advanced theory of the hydrogen bond The hydrogen bond remains a fairly mysterious object in the theoretical study of quantum chemistry and physics. Most generally, the hydrogen bond can be viewed as a metric dependent electrostatic scalar field between two or more intermolecular bonds. This is slig...
Crystalline porous materials made of molecular constituents networked through intermolecular hydrogen bonds (H-bonds) are termed hydrogen-bonded organic frameworks (HOFs) [1] by analogy to metal organic frameworks (MOFs) and covalent organic frameworks (COFs). Reversible bond formation frequently results ...
