Except where otherwise noted, textbooks on this site . Direct link to tyersome's post Good question! All of the attractive forces between neutral atoms and molecules are known as van der Waals forces, although they are usually referred to more informally as intermolecular attraction. LECTURE OBJECTIVES Chapter 10.2 Distinguish between adhesive and cohesive forces. The strengths of these attractive forces vary widely, though usually the IMFs between small molecules are weak compared to the intramolecular forces that bond atoms together within a molecule. As an example of the processes depicted in this figure, consider a sample of water. This behavior is most obvious for an ionic solid such as \(NaCl\), where the positively charged Na + ions are attracted to the negatively charged \(Cl^-\) ions. Creative Commons Attribution License (a) London Forces (Dispersion). The figure below shows a polyatomic anion named 2-phosphoglycerate interacting with two Mg +2 ions as it does in biological organisms, in the active site of an enzyme. hydrogen bonding. A sample of carbon dioxide H-bonding, Dipole-Induced dipole, Ion-Dipole, Dipole-dipole, Ion-Ion, Dispersion. The boiling point of a substance is proportional to the strength of its intermolecular forces the stronger the intermolecular forces, the higher the boiling point.
