Two liquids- one polar, one nonpolar- have the same molar mass. Which one has the higher boiling point?

a. it is impossible to say without additional information
b. the nonpolar liquid will have the higher boiling point, since its molecules are more loosely held together.
c. the nonpolar liquid will have the higher boiling point, since the polar molecules will repel each other and lower the boiling point.
d. the polar liquid will have the higher boiling point, since its molecules have dipole-dipole interactions.
e. they will have similar boiling points, since the dispersion forces depend upon molar mass

Answer:

D. the polar liquid will have the higher boiling point, since its molecules have dipole-dipole interactions.

Explanation:

Dipole-Dipole interactions 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.
