Would a cleaner with a higher/lower boiling point be more ideal for cleaning a polar substance?

Question

This is the question that my teacher posted, word by word. I am confused because I believe that it could go both ways. For example, lower boiling point would mean quicker evaporation, reducing chances of leaving residue. Yet, in higher boiling point, there are stronger intermolecular forces, and the atoms in the cleaner will be more attracted to each other than to molecules in the substance. I am not sure if my analysis is correct. Furthermore, my teacher gave no information about the substance.

Thank you!!

Answer 1

Cleaner with a higher boiling point has stronger intermolecular forces (which can be dispersion, dipole-dipole or H-bonding). Polar substances exhibit dipole-dipole interactions or H-bonding. Therefore, if the high boiling point of the cleaner is NOT due to dispersion forces, cleaner and the polar substance can interact (develop intermolecular interaction) better with each other (participate/contribute in each others intermolecular forces), and help remove the polar substance more efficiently.
