This video shows you how to draw the lewis dot diagram structure for SiCl4 - Silicon Tetrachloride. It also provides info on the molecular geometry, bond angle, and hybridization of SiCl4. The video also tells you if SiCl4 is polar or nonpolar. 1  Education. 2  Standard YouTube License.  SiCl4 or silicon tetrachloride is a non-polar molecule. It is used  in a variety of ways, but mainly in the production of very pure  silicon. A non-polar compound occurs when there is an equal sharing of electrons between two different atoms. Examples of household non-polar compounds include fats, oil and petrol/gasoline. Step 2: Identify each bond as either polar or nonpolar. (If the difference in electronegativity for the atoms in a bond is greater than 0.4, we consider the bond polar. If the difference in electronegativity is less than 0.4, the bond is essentially nonpolar.). If there are no polar bonds, the molecule is nonpolar. It is therefore a nonpolar molecule. None of the bonds in hydrocarbon molecules, such as hexane, C6H14, are significantly polar, so hydrocarbons are nonpolar molecular substances. A molecule can possess polar bonds and still be nonpolar. I understand that SiCl4 is a tetrahedral therefore it has a permanent dipole which makes it non-polar but I dont understand why the bonds are polar and the actual SiCl4 is not. The first one is polar bonds, which SiCl4 clearly has. The next is dissymmetry-in other words it can't be symmetrical. Because SiCl4 has a sp3 hybridization and is tetrahedral in shape, it is therefore symetrical and cannot be a polar molecule. Source(s): old chem notes. A non-polar compound occurs when there is an equal sharing of electrons between two different atoms. Examples of household non-polar compounds include fats, oil and petrol/gasoline. Therefore (per the oil and water rule of thumb), most non-polar molecules are water insoluble (hydrophobic) at room temperature. However many non-polar organic solvents, such as turpentine, are able to dissolve polar substances. When comparing a polar and non-polar molecule with similar molar masses, the polar molecule generally has a higher boiling point, because of the dipole-dipole interaction between their molecules. The most common form of such an interaction is the hydrogen bond, which is also known as the H-bond They may be classified as polar and non-polar. A non-polar compound occurs when there is an equal sharing of electrons between two different atoms. Examples of household non-polar compounds include fats, oil and petrol/gasoline. Therefore (per the oil and water rule of thumb), most non-polar molecules are water insoluble (hydrophobic) at room temperature When there are no polar bonds in a molecule, there is no permanent charge difference between one part of the molecule and another, and the molecule is nonpolar. For example, the Cl2 molecule has no polar bonds because the electron charge is identical on both atoms. It is therefore a nonpolar molecule. None of the bonds in hydrocarbon molecules, such as hexane, C6H14, are significantly polar, so hydrocarbons are nonpolar molecular substances. A molecule can possess polar bonds and still be nonpolar. (If the difference in electronegativity for the atoms in a bond is greater than 0.4, we consider the bond polar.

None of the bonds in hydrocarbon molecules, such as hexane, C6H14, are significantly polar, so hydrocarbons are nonpolar molecular substances. A molecule can possess polar bonds and still be nonpolar. SiCl4 is covalent compound. Si--Cl bond is polar because Cl is more electronegativity than Si. Structure of SiCl4 molecule is tetrahedral. THis structure is symmetry which brings to the non-polar characteristic of SiCl4 molecule. This is because all the dipole moment in Si--Cl bond cancel out each other. The bond between Si--Cl is covalent bond. SiCl4 molecules hold together by intermolecular Van der Waals force of attraction
