Silicon tetrafluoride (SiF4) is a tetrahedral molecule. Intermolecular force present in sulfur dioxide is dipole-dipole interactions. These results indicate that the structure of the complex requires tetracovalent rather than hexacovalent silicon and strong hydrogen bonds between methanol and each of the four fluorine atoms. Save my name, email, and website in this browser for the next time I comment. NH2Cl PH3 Then London forces are supposed to be greater in $\ce{SiCl4}$ due to its larger size and its boiling point should be higher than comparatively smaller $\ce{CCl4},$ but $\ce{CCl4}$ has higher boiling point..
