More information are available in ourPrivacy Statement. This material is incompatible with alkali metals and dimethyl sulfoxide. KEEP PEOPLE AWAY. Silicon tetrachloride (SiCl4), produced when both silicon and chlorine are combined at high temperatures, is used by the military to produce smoke screens. Keep reading to know more about the question "SiCl4 polar or nonpolar". In most of the times hybridization can be predicted from lewis structure. Although each Si-Cl bond is polar, the symmetrical arrangement of the bonds makes the molecule as a whole nonpolar. It is corrosive to metals and tissue in the presence of moisture.
