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
The resulting bond between nitrogen and hydrogen is a dative covalent bond. 2. Carbon monoxide (CO): Carbon monoxide features a triple bond between carbon and oxygen. Two of the three electron pairs in the triple bond are regular covalent bonds, while the remaining electron pair is a dative ...

1.2.4.3 Hydrogen bond Hydrogen bonding refers to a weak bond formation between a hydrogen atom attached to a strong electronegative atom and another atom of higher electronegativity. Hence, the hydrogen atom, which is connected to a highly electronegative atom (e.g., oxygen, nitrogen, and sulfur...
(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 ...
In the present work, we introduce two new metrics i.e. hydrogen-bond strength and charge-transfer between the donor/acceptor water molecules as a measure of hydrogen-bond rearrangement dynamics. Further, we also employ a simple model based on energy flux
The electronegativity value between metals and nonmetals is large, so they form ionic bonds with each other. Hydrogen usually acts as a nonmetal rather than as a metal. Sources Ingold, C. K.; Ingold, E. H. (1926). "The Nature of the Alternating Effect in Carbon Chains. Part V. A Di...
Cooperativity between the hydrogen bonding and halogen bonding in F3CX ··· NCH(CNH) ··· NCH(CNH) complexes (X=Cl, Br) MP2 calculations with the cc-pVTZ basis set were used to analyse the intermolecular interactions in F3CX···NCH(CNH)···NCH(CNH) triads (X=Cl, Br...
We combine photoelectron and x-ray absorption spectroscopy with density functional theory to derive a molecular orbital picture of the hydrogen bond in ice. We find that the hydrogen bond involves donation and back-donation of charge between the oxygen lone pair and the O–H antibonding orbitals ...
