A hydrogen bond is a kind of bonding that is present between an atom of hydrogen and a pair of other atoms having a high electronegativity. Hydrogen-bonding used to be competitively weaker than ionic bonding or covalent bonding, but it is stronger thanvan der Waals forces. Hydrogen bonding ca...

bond and are being constantly broken and reformed in water. The energy of hydrogen bonding is 1.0–10kcal/mol for each interaction. Each water molecule can potentially form four hydrogen bonds with surrounding water molecules. This is why theboiling pointof water is high for its molecular size....
Intermolecular hydrogen bonding of lactic acid in the vapor-phase causes it to form dimers and this dimerization greatly lowers its vapor-phase compressibility, Z. Intermolecular hydrogen bonding of lactic acid in the liquid phase causes it to form oligomers that increases its boiling point and ...
Hydrogen bonds are critical non-covalent bonds essential for the structural integrity and function of biological molecules such as DNA and proteins. They facilitate proper protein folding, stability, and specific ligand interactions, such as antigen-antibody binding. Hydrogen bonding involves a hydrogen ...

The hydrogen bonding patterns of melamine as well as mono- and diprotonated melamine have been analysed in five crystal structures of a solvate, a cocrystal and three organic and inorganic salts, namely, melamine DMSO solvate ([mel]路DMSO (1)), melamine theobromine cocrystal ([mel]路[TBR]3(...

Hydrogen bonding in small molecules Hydrogen bonding in biopolymers What you should be able to do Most students of chemistry quickly learn to relate the structure of a molecule to its general properties. Thus we generally expect small molecules to form gases or liquids, and large ones to exist...
