WebSep 23, 2015 · Explanation: London dispersion force (LDF) depends on the surface area of interacted particles. Moreover, more electrons results in larger atoms size and therefore, stronger LDF. This is also derived from the fact that higher number of electrons will increase the chance of forming what is called induced dipole (also called polarizability) which ... WebAug 9, 2024 · There are 3 types of intermolecular force: London Dispersion, Dipole-Dipole (Example: Two N a C l) and Ion-Dipole (Example: M g + and H C l) Dipole- Dipole occurs between polar molecules Ion- Dipole occurs between an ion and polar molecules London Dispersion occurs between the nonpolar molecules. Q13.6 WebMar 7, 2015 · A measure of the strength of the LDFs will be the compounds' boiling point. The stronger the dispersion forces, the higher the boling point will be. If you take into account the two rules I've mentioned, you'll end up, in order of increasing boiling point, i.e increasing strength of LDFs, with CH 4 < C2H 4 < C2H 6 < C3H 8 < C4H 10 cool photography spots in las vegas

WebLondon dispersion forces definition. London dispersion forces are a temporary attraction between two adjacent atoms. One atom's electrons are unsymmetrical, which creates a temporary dipole. This dipole causes an induced dipole in the other atom, which leads to the attraction between the two.
