You can see immediately that the SI unit has to be C m. Convince yourself that if the system as a whole is electrically neutral, so that there is as much positive charge as negative charge, the dipole moment so defined is independent of the position of the point O. So the vector sum of three bond dipole moment is zero. So you must find the most polar bond, or bond which has the greatest electronegativity difference. Relevance. If the molecule has some net dipole moment then it means the molecule is over all polar. The atomic radiusis: Find out the solubility of $Ni(OH)_2$ in 0.1 M NaOH.

The dipole moment of nonpolar molecules is always zero. CBr4 (Carbon tetrabromide) is also a similar compound having polar C-Br bonds with some dipole moment value but the entire molecule is nonpolar because of the net-zero dipole. The total molecular dipole moment may be approximated as the vector sum of the individual bond dipole moments. 1. The size of a dipole is measured by its dipole moment (\(\mu\)).
