Bond polarity, driven by differences in electronegativity, explains why some molecules dissolve in water, why others don’t, and why substances have different boiling points. Polar bonds have unequal ...

Many properties of molecules cannot be predicted from the properties of the atoms they consist of. These properties only ...

Electronegativity and molecular polarity are central to understanding chemical bonding. By combining periodic trends with molecular geometry, you can predict whether a molecule is polar or nonpolar.

In molecular crystals that exhibit singlet fission, quantum yields depend strongly on intermolecular configurations that control the relevant electronic couplings. Here, we explore how noncovalent ...

Solubility functions by a group of rules that determine how dissolvable a substance (solute) is in solvent and depends entirely on the physical and chemical properties of the solute and solvent. That ...

THERE is an increasing tendency on the part of organic chemists to apply the Berzelius dualistic theory, in a modified form, to organic compounds. In many theories of valency, individual groups are ...
