I can justify that $\ce{SF4}$ has the higher boiling point because it is more polar since its Lewis structure has a lone pair on the sulfur atom, and so it experiences greater dipole-dipole forces. Selenium tetrafluoride is an inorganic compound. Why does phosphine have a dipole moment and a higher boiling point than carbon tetrafluoride? However, since SiF4 is tetrahedral, this same force is exerted in four directions opposite to each other. significant component, A:Hydrogen bonding is the type of intermolecular or intramolecular force of attraction that occurred, Q:Rank these substances from strongest intermolecular forces to weakest. The former is termed an intramolecular attraction while the latter is termed an intermolecular attraction. As a result, there are no lone pairs and two bond pairs. A:If the size of the element increases, then the dispersion forces also increase. a. So now we can define the two forces: Intramolecular forces are the forces that hold atoms together within a molecule. (3.16) and silicon (1.90) is quite high, the bonds within the molecule are polar covalent. Intermolecular forces are Hydrogen bonds.
