Dipole moment is measured in
Correct answer: A. debye units
- A. debye units
- B. joules
- C. angstroms
- D. moles
Explanation
Dipole moment is the product of the magnitude of the separated charge and the distance between the centres of charge, and it is quoted in debye, with water at about 1.85 D. A larger value means a more polar molecule and therefore stronger dipole to dipole attraction and a higher boiling point. Angstroms measure length and joules measure energy, so neither can express this quantity.

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.
