Web6.3.2 Van der Waals Force. van der Waals interaction is primarily responsible for these intermolecular forces, the two molecules of the same material (though electrically neutral) are brought together, the nonbonding electrons of both overlap each other and result in the repulsive force due to the presence of the surface electron. WebSep 16, 2024 · Intermolecular forces are generally much weaker than covalent bonds. For example, it requires 927 kJ to overcome the intramolecular forces and break both O–H bonds in 1 mol of water, but it takes only about 41 kJ to overcome the intermolecular attractions and convert 1 mol of liquid water to water vapor at 100°C. (Despite this … WebLondon Dispersion Forces. The London dispersion force is the weakest intermolecular force. The London dispersion force is a temporary attractive force that results when the electrons in two adjacent atoms occupy positions that make the atoms form temporary dipoles. This force is sometimes called an induced dipole-induced dipole attraction. farm fresh beef prices
