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 ...
When present, these hydrogen bonds also increase the boiling point and water solubility of a compound, and may have an important role in determining the shape of very large molecules such as proteins. View article Review article Solid-state NMR and protein dynamics ...

There are different types of intermolecular forces of attractions and it all can affect some of the properties of the molecules or compounds. Hydrogen Bonding, London Dispersion Forces, and Dipole-Dipole Forces are some of the known intermolecular forces o...
The bonds are stronger in solids(more closely packed together) than in liquids(molecules are loose) Dipole-Dipole Forces ? Not as strong as an ionic bond but is usually stronger than London forces ? Great effect only when the polar molecules are close together ? Hydrogen bonding is a type ...
For example, the dipole moment of halogen–hydrogen bonds increases from HI to HF according to increase of electronegativity of the halogen atoms (see Table 4.1). TABLE 4.1. Electric dipole moments of some of halogen–hydrogen molecules MoleculeDipole moments Empty Cell10–30 C mD HF 6.37 1.91...
