and as a result, fluorine pulls all the electrons towards itself and becomes the negative pole. Hydrogen, in turn, has an excess of protons and becomes the positive pole. Such molecules with permanent dipole moments are called polar molecules. ...

Such an effect can account for the reversible enhancement of the conductivity of polyaniline that is brought about by complexation with polar molecules such as water.doi:10.1016/0379-6779(94)90173-2ShackletteL.W.Synthetic MetalsShacklette L W.Dipole and Hydrogen-Bonding Interactions in Polyaniline ...
- Ice has an open structure in which each oxygen atom forms 2 hydrogen bonds in addition to its own 2 covalent bonds. - the 4 bonds are tetrahedrally arranged around the oxygen atom H Cl H Cl H Cl H Cl - When ice melts, many of they hydrogen bonds break, open structure collapses, ...
In contrast to the permanent dipole of hydrogen bonds, the van der Waals bonds amount to a fluctuating dipole generated by the mutual influence of the motion of electrons of atoms. At any time there may be more electrons on one side of the atomic nucleus than on the other, thus creating ...
7 , hydration water molecules on protein surfaces form networks of hydrogen bonds. Due to the directionality of hydrogen bonds, the orientation of hydration water molecules is restrained by polar protein atoms and adjoining hydration water molecules. In this regard, molecular dynamics simulation ...
aThis dipole moment causes water molecules to be attracted to each other (the slightly positive hydrogen side being attracted to the slightly negative oxygen side) and to other polar molecules. This attraction is named hydrogen bonding, and explains several of the water properties. 这偶极矩造成水...
