Of the three forces, ionic, dipole- dipole, and London disperison forces, which is the strongest?
Ionic forces are the strongest, dispersion forces are the weakest.

But the same computer. But that's ok.
To determine which of the three forces is the strongest among ionic, dipole-dipole, and London dispersion forces, we need to understand the nature of each force.
1. Ionic Forces: These forces result from the attraction between positively and negatively charged ions. Ionic compounds are formed when one or more electrons are transferred from a metal to a non-metal, creating a strong electrostatic bond. Ionic forces are generally the strongest among the three forces due to the significant difference in electronegativity of the atoms involved.
2. Dipole-Dipole Forces: These forces occur between polar molecules, where the positive end of one molecule attracts the negative end of another molecule. Dipole-dipole forces are weaker than ionic forces because they depend on the polarity of the molecules involved and are significantly influenced by the electronegativity difference.
3. London Dispersion Forces: Also known as Van der Waals forces, London dispersion forces arise due to temporary shifts in electron distribution, resulting in temporary dipoles. These forces are present in all atoms and molecules but are particularly significant in non-polar molecules. London dispersion forces are generally weaker than both ionic and dipole-dipole forces.
Considering the above explanations, we can conclude that ionic forces are the strongest among the three forces, followed by dipole-dipole forces, and then London dispersion forces.
