Bond polarity is all about how atoms share electrons—and when that sharing isn’t equal, fascinating things happen. From electronegativity differences to molecular geometry, these factors decide ...

Researchers have observed steric effects—the interactions of molecules depending on their spatial orientation (not just between their electrons involved in bonding)—in a chemical reaction involving ...

Engineering researchers have developed a technique to isolate a single water molecule inside a buckyball and drive motion of the "big" nonpolar ball through the encapsulated "small" polar H2O molecule ...

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 ...
