Answer to Question #226707 in General Chemistry for jewinafer sorita

Question

In terms of intermolecular forces, explain WHY we see this general trend in boiling points, for compounds of equivalent formula mass. How does the presence of a dipole moment affect the strength of intermolecular interactions?

Answer 1

Intermolecular forces (IMFs) can be used to predict relative boiling points. The stronger the IMFs, the lower the vapor pressure of the substance and the higher the boiling point.
