HF + NaF → Na+ + HF2¯ At lower temperatures (below 200°C), HF forms molecular aggregates that are held by hydrogen bonding containing linear chains of –F—H—-F—H—- F—H—-. However, above this temperature the weak hydrogen bond breaks producing monomolecular HF. Thermal dissoci...
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
Intramolecular hydrogen bonding will not cause molecules to repel each other, but it will reduce the attractive interactions between molecules. This is simply because in o-nitrophenol the OH group forms a hydrogen bond with the adjacent nitro group and that reduces its ability to form h...
Intermolecular hydrogen bonding is responsible for the high boiling point of water (100 °C). This is because of the strong hydrogen bond, as opposed to other group 16 hydrides. Intramolecular hydrogen bonding is partly responsible for the secondary, tertiary, and quaternary structures of proteins ...
Molecules, Vol. 19, Pages 15783-15785: Special Issue: Intramolecular Hydrogen BondingIntramolecular hydrogen bonds play critical structure- and function-serving roles in biological and synthetic molecular systems. This special issue, through eight contributions, showcases the prominenc...
Hydrogen bonding (H-bonding) of water molecules confined in nanopores is of particular interest because it is expected to exhibit chemical features different from bulk water molecules due to their interaction with the wall lining the pores. Herein, we show a crystalline behavior of H-bonded water...
It plays a particularly important role in acid-base chemistry with many reactions exchanging protons between soluble molecules. As the only neutral atom with an analytic solution to the Schrödinger equation, the study of the energetics and bonding of the hydrogen atom played a key role in the ...

To improve reactivity with methane and ensure a high hydrogen adsorption platform pressure, partial substitution of Fe with Ni, which has a smaller bonding energy with methane ligand, is beneficial. In this work, we prepared ZrMnFeNi alloys with different Ni stoichiometric ratios by suspension ...
(pH = 7.4) for all peptides. TIP3P water molecules49were used to solvate the system; the smooth particle-mesh Ewald method50was used to calculate the long-range electrostatic interactions; Na+and Cl−ions were added to the system to maintain the specific ionic strength and net charge ...
