Carbon tetrachloride,CCl4, has a net dipole moment of zero.Even though each of the four C-Cl bond is distinctly polar, the resultant moment of any three of them is equal in magnitude but opposite in direction to the moment due to the fourth one. So, the molecule’s net dipole moment is zero, and it is non-polar.
