Why C2H4Cl2 is polar
Both C–Cl bonds meet at the same tetrahedral carbon in 1,1-dichloroethane. Their transverse components partly cancel, but the dipole along the substituted end remains.
What to notice
The formula C2H4Cl2 also describes 1,2-dichloroethane; the position numbers are necessary to identify the structure.
