Which best describes the relationship between melting/boiling points and IMFs? The larger the IMF the higher the melting/boiling point, because more heat energy will be required to overcome these attractions to cause a phase change. The larger the IMF the lower the melting/boiling point, because less heat energy will be required to overcome these attractions to cause a phase change.

The correct answer is: The larger the IMF the higher the melting/boiling point, because more heat energy will be required to overcome these attractions to cause a phase change.<br /><br />Intermolecular forces (IMFs) are the forces of attraction between molecules. The strength of these forces determines the physical properties of a substance, including its melting and boiling points. The stronger the IMFs, the more energy is required to overcome them and cause a phase change. Therefore, substances with stronger IMFs will have higher melting and boiling points.
