About Dipole Moment
Dipole moment measures the separation of positive and negative charge in a bond or molecule, with magnitude related to charge and distance, μ = q r. Questions distinguish polar bonds from polar molecules by considering bond direction, molecular geometry and whether individual bond moments cancel through symmetry.
