Jan 13, 2012 · C-Cl bond is polar due to Chlorine being a more electronegative atom than Carbon. This creates a dipole where Chlorine is 'delta negative' or slightly negative and Carbon is 'delta positive' or slightly positive. This dipole causes the bond to be polar as the electrons will be pulled more towards the Chlorine atom.
CH3Cl has larger dipole moment than CH3F because dipole moment is based on the product of distance and charge, and not just charge alone. Fluorine is more electronegative than chlorine, but, the carbon-fluorine bond is also much shorter than the carbon-chlorine bond: 139 pm vs 178 pm.

Jan 01, 2019 · This is because it is possible for a molecule to be nonpolar yet still have polar bonds. One example of this phenomenon is carbon dioxide. Although there are polar bonds found within a carbon dioxide molecule, the molecule overall is nonpolar because the dipole moments of the molecule neutralize one another. Similarily dipole moments of CHCl3, CH2Cl2 and CH3Cl is calculated. But dipole moment of CCl4 is 0 because the vector sum of dipoles formed in CCl4 is zero.
