The bond moment of C-Cl in m-dichlorobenzene is 0.6 D , then its dipole moment is

Dipole minutes happen when there is a division of charge. They can happen between two particles in an ionic bond or between iotas in a covalent bond; dipole minutes emerge from contrasts in electronegativity. 

The bigger the distinction in electronegativity, the bigger the dipole minute. The separation between the charge partition is additionally a main figure the extent of the dipole minute.
