Question

Tetrachloromethane has no dipole moments though it has polar bonds

Answer 1

Answer:

Now consider tetrachloromethane (CCl4) and dichloromethane (CH2Cl2). Both molecules have polar C—Cl bonds with the negative ends of the dipoles pointed toward the chlorine atoms. However, CCl4 does not have a dipole moment because the vector sum of the symmetrically arranged C—Cl bonds around carbon is zero.
