Dipole Molecule - English Definition & Meaning

Definition

A dipole molecule is a molecule with a partial positive charge on one side and a partial negative charge on the other. This charge separation creates an electrical dipole moment. Water (H₂O) is a classic example, with oxygen being slightly negative and hydrogen being slightly positive. These partial charges arise from differences in electronegativity between atoms. Unlike nonpolar molecules, dipoles interact strongly with electric fields. They're kinda like tiny magnets with a positive and negative end.

Etymology

The term "dipole" comes from the Greek words "di," meaning "two," and "polos," meaning "axis" or "pole." It refers to the two opposing poles of charge within the molecule. The concept was developed in the early 20th century with advancements in understanding chemical bonding. Understanding dipole moments helped explain many chemical and physical properties. It is directly related to electronegativity differences.
