As per the lewis structure of SiCl4, the silicon central atom bonded to 4 chlorine atoms and have a zero lone pair on it. Therefore, we are left with 24 valence electrons more. The significant production in the aerospace fleet all over the world is casting a positive impact on the global . The molecular geometry of SiCl4 is tetrahedral and its electron geometry is also tetrahedral because as per VSEPR theory, molecular shape considers only bond pairs or atoms while electron geometry considers bonded atoms as well as lone pairs present on the central atom. The ferrosilicon route is most common. Therefore, 4 chlorine atoms will make the bond with silicon. According to the VSEPR theory, when a central atom(silicon) is attached to four bonded atoms(chlorine) then an electron pair around the central atom repel each other as a result all corners atoms(chlorines) spread out as much as they can and takes the place where the repulsion is minimum and stability is much better. The AsF5 molecule is trigonal bipyramidal. Dipole moment generated along with the bond(Si-Cl) due to the separation of charge induced on atoms, this charge is induced because the electronegativity of chlorine is 3.16 and for silicon, it is 1.90.
