SiCl4 only exhibits London dispersion forces. How many covalent bonds does SiCl4 have? It has 4 covalent bonds which constitute 2 double bonds with each oxygen atom. Which of the following species are tetrahedral: SiCl4, SeF4, XeF4, CI4, CdCl42-SiCl4. We've got four Cl's there, so if we multiply that all together we've got 28 plus 4: 32 total valence electrons. Due to their different three-dimensional structures, some molecules with polar bonds have a net dipole moment (HCl, CH2O, NH3, and CHCl3), indicated in blue, whereas others do not because the bond dipole moments cancel (BCl3, CCl4, PF5, and SF6).
