WebBonds and intermolecular forces have one very fundamental thing in common. Both mechanisms are electrostatic forces of attraction (Coulombic forces) between areas of charge. The primary difference between bonds and intermolecular forces is the locations of the areas of charge and the magnitudes of the areas of charge. WebInter molecular forces hold multiple molecules together and determine many of a substance’s properties. 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. We will consider the various types of IMFs in the next ...

WebThe phase in which a substance exists depends on the relative extents of its intermolecular forces (IMFs) and the kinetic energies (KE) of its molecules. IMFs are the various forces of attraction that may exist between the atoms and molecules of a substance due to electrostatic phenomena, as will be detailed in this module. WebSteps for Identifying the Strongest Types of Intermolecular Forces: Step 1: Draw the Lewis structure for each molecule. Look for the presence of highly electronegative atoms (such as O, N, F).

WebIntermolecular Forces Coulomb’s Law is used to explain IMF’s. Opposite charges attract. The stronger these attractions, the stronger the IMF between molecules. Intermolecular = Between Molecules The stronger the IMF between molecules, the more difficult it is to separate those molecules resulting in: High melting point High boiling point WebA molecule will have a higher boiling point if it has stronger intermolecular forces. Basically if there are more forces of attraction holding the molecules together, it takes more energy to pull them apart from the liquid phase to the gaseous phase.

WebThe IMFs of attraction between two different molecules are called adhesive forces. Consider what happens when water comes into contact with some surface. If the adhesive forces between water molecules and the molecules of the surface are weak compared to the cohesive forces between the water molecules, the water does not “wet” the surface.
