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

Molecular polarity and intermolecular forces explain why substances dissolve, boil, or stick together the way they do. From the shape of a molecule to the pull of its atoms, polarity determines ...

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 ...
