C-Cl bonds are actually polar, as chlorine is more electronegative than carbon. Polar "In chemistry, polarity is a separation of electric charge leading to a molecule or its chemical groups having an electric dipole or multipole moment. A polar molecule always contains polar bonds, but some molecules with polar bonds are nonpolar. It's essential for predicting molecular geometry, molecule polarity, and reactivity in a compound.
