While selecting the center atom, always put the least electronegative atom at the center. The next step is to calculate the number of bond (covalent or ionic) connectivity between the atoms. Answer: SiCl4 (Silicon Tetrachloride) is a nonpolar molecule because all of the four chlorine molecules are equally spaced around the central silicon atom in a tetrahedral structure. But the four Si-Cl bonds are comparatively polar due to the electronegativity difference between silicon and chlorine atom (electronegativity of silicon and chlorine is 1.9 and 3.16 in Pauling scale). Although each Si-Cl bond is polar, the symmetrical arrangement of the bonds makes the molecule as a whole nonpolar.
