boiling and melting points

Postby hannabarlow1A » Tue Jul 16, 2019 8:34 am

What is the relationship between boiling points, melting points, and a molecule's size and bonds?

A larger molecule will in general have more electrons, meaning the dispersion forces between its molecules will be stronger. This will raise both its melting and boiling points. However, substances that experience stronger intermolecular forces will have higher melting points than those that only experience dispersion forces between their molecules
