The strongest H-bonds are obtained as a result of a concerted push–pull effect of four peripheral water molecules, which polarize the electron density in a way that supports charge transfer and partial covalent character of the targeted H-bond. For water molecules with tetra- and penta...
One factor that makes water unique even among other hydrogen-bonded liquids is its very small mass in relation to the large number of hydrogen bonds it can form. Owing to disruptions of these weak attractions by thermal motions, the lifetime of any single hydrogen bond is very short — on ...
Hydrogen bond in water The most ubiquitous, and perhaps simplest, example of a hydrogen bond is found betweenwatermolecules. In a discrete water molecule, water has two hydrogen atoms and one oxygen atom. Two molecules of water can form a hydrogen bond between them. The oxygen of one water ...
The hydrogen bond is important in water because without it, life as we know it, would not be able to exist on Earth. We know that without water, we... See full answer below. Learn more about this topic: Properties of Water | Physical & Chemical ...
(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 subject area: Materials Science A hydrogen bond (H-bond) is a partial intermolecular bonding interaction between a lone pair on an electron-rich atom, mainly the second-row elements fluorine, oxygen, or nitrogen, and the antibonding molecular orbital of H and a more electronegative atom. ...
The existence of bifurcated hydrogen bonds (BHB) between three molecules as a major feature of the structure of liquid water was postulated recently to account for the remarkable effect of temperature on the O–H stretching bands in the Raman spectra. As a corollary, there should be two kinds...
