Molecules having two equal and opposite charges separated by certain distance are said to possess an electric dipole. In the case of such polar molecules, the centre of negative charge does not coincide with the centre of positive charge. The extent of polarity in such covalent molecules can be described by the term Dipole moment.
Dipole moment can be defined as the product of the magnitude of the charge and the distance of separation between the charges.
It is represented by the Greek letter 'm'. Mathematically it is equal to
dipole moment (m) = charge (e) x distance of separation (d).
It is expressed in the units of Debye and written as D
(1 Debye = 1 x 10-18e.s.u cm)
Dipole moment is a vector quantity and is represented by a small arrow with tail at the positive centre and head pointing towards a negative centre.
