Measurement of the degree of polarity is___________________?
Correct answer: D. Dipole moment
- A. Electron affinity
- B. Ionic character
- C. Ionization energy
- D. Dipole moment
Explanation
Dipole moment measures the separation of positive and negative charge in a molecule, so it gives a quantitative measure of molecular polarity. Ionic character describes the extent of charge separation but is not the direct molecular measurement. Students may choose b because greater ionic character usually increases polarity, but the measured quantity is dipole moment.

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.
