A bond dipole moment refers to the separation of electric charge within a chemical bond. It can be described as the degree of polarity or asymmetry between two atoms within a molecule. Synonyms for bond dipole moment include molecular dipole moment, chemical polarity, electronegativity difference, and bond polarity. These terms all refer to the degree to which the electrons are shared between two atoms in a chemical bond. In general, a larger bond dipole moment indicates a stronger polarity, resulting in a higher degree of electronegativity difference between the atoms involved in the bond. Understanding bond dipole moment is crucial in determining many chemical properties, including solubility, reactivity, and physical characteristics.
