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 ...

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.
