Answer:
D. the polar liquid will have the higher boiling point, since its molecules have dipole-dipole interactions.
Explanation:
<em>Dipole-Dipole interactions</em> take place only between polar molecules.
They consist of attractions between the negative end of a polar molecule and the positive end of another polar molecule. For example, between the O atom and the H atom in water.
These attractions are not present in a non-polar liquid, so its molecules will be more loosely held together and its boiling point will be lower.
