Dispersion forces usually increase with molar mass (more electrons), or size of the atom. Here is why: PH3 is called phosphine and it is quite toxic and flammable. Solve Study Textbooks Guides. As the intermolecular forces increase, higher energy is needed to separate the GeH4 . Among all the intermolecular forces, dispersion force is the weakest. Compounds with stronger intermolecular forces have higher boiling points. Why is iodine a solid? The relative strength of the four intermolecular forces is: Ionic > Hydrogen bonding > dipole dipole > Van der Waals dispersion forces. MgS——MgS 10. Intermolecular forces of attraction in liquid chloroethane are larger due to dipole-dipole attraction; thus a higher boiling point for chloroethane. Considering this fact, it is not surprising that variations in the magnitude of dispersion forces affect the boiling point much more than variations in the magnitude of the dipole-dipole attractions. Due the very large size of SbH3, its weak VanderWall forces dominate the H-bonding of NH3. In the following description, the term particle will be used to refer to an atom, molecule, or ion.

Arrange them from highest to lowest intermolecular forces. If the temperature of a liquid decreases, the equilibrium vapor pressure increases. An intermolecular force ( IMF) (or secondary force) is the force that mediates interaction between molecules, including the electromagnetic forces of attraction or repulsion which act between atoms and other types of neighboring particles, e.g. As was the case for gaseous substances, the kinetic molecular theory may be used to explain the behavior of solids and liquids. When it melts, the ionic bond is broken which requires more energy than SbH3 which has just VanderWall. Dipole forces are stronger than London forces so it takes more energy to separate the molecules (which is what happens when something boils 4) The stronger the intermolecular force the higher the melting and boiling point Choose the molecule or compound that exhibits dipole-dipole forces as its strongest intermolecular force. Dipole-dipole interaction 3. Question: 3) Antimony trihydride (SbH3) has a higher boiling point than ammonia (NH3). CH3OH - Hydrogen Bonding 6. (C) the higher the vapor pressure.
