Which Of The Following Statements Are True? Select All That Apply.

A. All other factors being the same, dispersion forces between linear molecules are greater than dispersion forces between molecules whose shapes are nearly spherical.

B. 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 .

C. For molecules with varying molecular weights, the dispersion forces may not become stronger as the molecules become more polarizable.

D. The smaller the atom, the less polarizable it is.

E. In terms of the total attractive forces for a given substance, dipole-dipole interactions, when present, are always larger than dispersion forces.

Expert Solution

A. All other factors being the same, dispersion forces between linear molecules are greater than dispersion forces between molecules whose shapes are nearly spherical.

True. Because spherical molecules have smaller surface area

B. 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

False. Because on going down from Fluorine to Iodine, the surface area increases

C. For molecules with varying molecular weights, the dispersion forces may not become stronger as the molecules become more polarizable.

True. Because, the polarizability increases with size

D. The smaller the atom, the less polarizable it is.

True. Electrons are firmly held by the nucleus in smaller molecules

E. In terms of the total attractive forces for a given substance, dipole-dipole interactions, when present, are always larger than dispersion forces.

False. Dispersion forces can be stronger than the dipole-dipole interactions in bigger molecules
