Chemistry - CHEMICAL BONDING Question with Solution | TestHub

Symmetrical molecules are generally non-polar although they have polar bonds. This is because bond dipole of one bond is cancelled by that of the other. ${\mathrm{BF}}_3,{\mathrm{SiF}}_4$ and ${\mathrm{XeF}}_4$ being symmetrical as non-polar. ${\mathrm{SF}}_4$ is unsymmetrical because of the presence of a lone pair of electrons. Due to which it is a polar molecule.
