The dipole moment (m) of a molecule is the vector sum of the dipole moment of the individual bonds in some cases these sums cancel each other while in other cases they enhance each other. Given the bond moments of H-C(0.4) and C-Cl(1.5) predict the dipole moment and thus the polarity of CH³Cl, CH²Cl², CHCl³ and CCl³
