Dipole moment is expresssed in what units?

Dipole moment is expressed in Debye units.

Dipole moment

  • The dipole moment of a single bond in a polyatomic molecule is known as the bond dipole moment, and it is different from the dipole moment of the molecule as a whole.
  • It is a vector quantity, i.e. it has magnitude as well as definite directions.
  • Dipole Moment (µ) = Charge (Q) * distance of separation (r)
  • When there is a difference in the electronegativity of two atoms involved in a bond, a dipole moment happens. The larger the electronegativity difference between the two atoms, the larger the bond’s dipole moment and polarity.
  • In the case of a polyatomic molecule, the molecule’s dipole moment is the vector sum of the all-present bond dipoles in the molecule.
