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.tructure of SiCl4 molecule is tetrahedral.
