Chapter 11: 1-3 Homework

Reading Preparation

Textbook assignment: Read Kotz and Triechel, Chemistry and Chemical Reactivity Chapter 11: Sections 1 to 3

Study Notes

Intermolecular forces called van der Waals forces hold molecules together to form solids. As with all chemical "bonds", the forces have their basis in electrical charges, in the electrons in their shells and protons of the nucleus of the atoms. But the bonds between molecules are much weaker than the electron-sharing bonds within molecules that we studied in chapters 7-9.

Key Formula
