Which of the following statements are true? Select all that apply. O For molecules with varying molecular weights, the dispersion forces may not become stronger as the molecules become more polarizable. O The smaller the atom, the less polarizable it is. O In terms of the total attractive forces for a given substance, the contribution of dipole-dipole interactions, when present, are always larger than the contributions of dispersion forces. O For the halogens, the dispersion forces increase while the boiling points decrease as you go down the column in the periodic table from F2 to I2 O All other factors being the same, dispersion forces between linear molecules are greater than dispersion forces between molecules whose shapes are nearly spherical.

Recall that for molecules of similar size and mass, dipole-dipole interactions are typically stronger than dispersion forces. It's both the size of the molecule and the strength of the dipole
and dipole-dipole forces.
