Dipole Moment

[Nicole Jakiel 4F]

What are dipole moments, and how do you know when they occur?

[Sona Hakobyan 3J]

Dipole moments occur when there is a separation of charge. They can occur between two ions in an ionic bond or between atoms in a covalent bond; dipole moments arise from differences in electronegativity. The larger the difference in electronegativity, the larger the dipole moment. The distance between the charge separation is also a deciding factor into the size of the dipole moment. The dipole moment is a measure of the polarity of the molecule.

Hi! Dipole moments occur when a molecule has partially negative and a partially positive end. For example, H2O molecules are polar and have dipole moments during which the positive H ends are attracted to the negative O ends of different particles.
