Define Hydrogen bonds. Hydrogen bonds synonyms, Hydrogen bonds pronunciation, Hydrogen bonds translation, English dictionary definition of Hydrogen bonds. n. A chemical bond in which a hydrogen atom of one molecule is attracted to an electronegative atom
Moreover, the strength provided by hydrogen bonds is low compared to that of most covalent bonds, providing the basis for fast and easy linkage and breakage of hydrogen bonds. Moreover, self-healing hydrogels prepared by hydrogen bonding can achieve better mechanical properties while maintaining ...
When it was realized that the other molecule of life, DNA, owes its double helix structure to specific hydrogen bonds between A–T (two) and C–G (three) base pairs, the interest in hydrogen bonding grew dramatically. While hydrogen bonding could be readily seen in water and DNA, it was...
(HOFs)23,24,25,26. Viewing from the linkage topologies, HOFs are constructed by the weakly intermolecular interactions of hydrogen bonds. This distinct linkage topology endows HOF with a much milder crystallization process, wherein the high pressure and temperature or strong acidity that are usually...
formation of strong multiple H-bonds between hydrophobic urea groups. Therefore, the clustered structures protected against the influence of water molecules to induce greater electron delocalization through the formation of strong multiple H-bonds, leading to red fluorescence in a water-saturated hydrogel...

in water. It is a weak acid, but will dissolve most silicates and hence can be used to etch glass. As the interatomic distance in HF is relatively small, the H–F bond energy is very high and hydrogen fluoride is not a good proton donor. It does, however, form hydrogen bonds. ...

3.1 Definition ChEBI: A hydrate that is the dihydrate form of disodium hydrogenphosphate 3.2 Description Disodium hydrogen phosphate dihydrate, with the chemical formula Na2HPO4·2H2O, has the CAS number 10028-24-7. It appears as a white, crystalline powder with no odor. The basic structure of ...
The computational insights unveiled the formation of a pivotal intermediate Int1-SR, stabilized by a combination of two hydrogen bonds and one O‒H···π interaction involving the catalyst (S)−4a, hydrogen peroxide, and 1aa. This stabilization manifests as a substantial energy reduction of...
