Molecular weights, dipole moments, and boiling points of several simple organic substances.
Moving from left to right, do the dispersion forces get stronger, get weaker, or stay roughly the same in the molecules shown above?
We have to determine what happens to the strength of dispersion forces in the given trend.
Dispersion forces occur in all types of compounds, no matter whether they are polar or nonpolar.
Dispersion forces are a result of inhomogeneity in electron cloud distributionaround the molecules.
