what are the different types of intermolecular forces of attraction from strongest to weakest?
237590
In order from strongest to weakest, the intermolecular forces given in the answer choices are: ion-dipole, hydrogen bonding, dipole-dipole, and Van der Waals forces. Ionic bonding is stronger than any of the given intermolecular forces, but is itself NOT an intermolecular force.

CF4 only has dispersion forces. OF2 is a polar molecule, so will have both dipole-dipole interactions and dispersion forces. ... Boiling and melting points generally are an indication of the strength of intermolecular forces (IMF) present; they are a measure of the energy needed to overcome those forces.

Greater electronegativity of the hydrogen bond acceptor will lead to an increase in hydrogen-bond strength. The hydrogen bond is one of the strongest intermolecular attractions, but weaker than a covalent or an ionic bond. Hydrogen bonds are responsible for holding together DNA, proteins, and other macromolecules.

Covalent bonds do not dissolve in water, but some covalent compounds do. Covalent molecules are attracted to each other by various intermolecular forces such as H-bonds, dipole-dipole forces, and London dispersion forces. Water molecules are attracted to each other by strong H-bonds.

The more kinetic energy, the weaker the intermolecular forces. Liquids have more kinetic energy than solids, so the intermolecular forces between liquid particles tend to be weaker.

London dispersion forces, under the category of van der Waal forces: These are the weakest of the intermolecular forces and exist between all types of molecules, whether ionic or covalent—polar or nonpolar. The more electrons a molecule has, the stronger the London dispersion forces are.

All will exhibit the dispersion force, with H2Te being the strongest with the most electrons. H2S, H2Se and H2Te exhibit dipole-dipole intermolecular forces while H2O exhibits hydrogen bonding.

Water has the strongest intermolecular forces (hydrogen bonds) of all the substances used. Glycerine and methylated spirits also have hydrogen bonds, but these intermolecular forces are slightly weaker than in water.

polar/nonpolar? Put the following in order from greatest to least intermolecular forces: H2O, LiOH, CO2. explain your reasoning. Since the bonds are polar covalent by their electronegativities but the molecule is nonpolar, london dispersion is the greatest because it is nonpolar.

When simple molecular substances melt or boil, it is these weak intermolecular forces that are overcome. The covalent bonds are not broken. ... In general, the bigger the molecule, the stronger the intermolecular forces, so the higher the melting and boiling points.

Ionic compounds exhibit electrostatic intermolecular forces that form strong bonds with other ionic species. Covalent compounds exhibit van der Waals intermolecular forces that form bonds of various strengths with other covalent compounds.

Covalent and ionic bonds are both typically considered strong bonds. However, other kinds of more temporary bonds can also form between atoms or molecules. Two types of weak bonds often seen in biology are hydrogen bonds and London dispersion forces.

Dipole-dipole forces have strengths that range from 5 kJ to 20 kJ per mole. They are much weaker than ionic or covalent bonds and have a significant effect only when the molecules involved are close together (touching or almost touching).

Dipole-dipole forces are attractive forces between the positive end of one polar molecule and the negative end of another polar molecule. ... They are much weaker than ionic or covalent bonds and have a significant effect only when the molecules involved are close together (touching or almost touching).

1 Answer. Chuck W. Stronger intermolecular forces increase the energy difference between the liquid and gas phases of any substance. This slows the rate of evaporation and decreases the equilibrium vapor pressure.
