Leafy Greens. Green leafy vegetables are the richest sources of vitamin K. The highest sources include parsley, kale and Swiss chard. One cup of raw parsley contains 984 micrograms of vitamin K; a cup of raw kale contains 472 micrograms; and 1 cup of raw Swiss chard contains 299 micrograms.
London dispersion forces, under the category of van der Waal forces: These are the weakest of the intermolecular forces and exist between all types of molecules, whether ionic or covalentâpolar or nonpolar. The more electrons a molecule has, the stronger the London dispersion forces are.
London dispersion forces are a type of force acting between atoms and molecules. They are part of the van der Waals forces. The LDF is named after the German-American physicist Fritz London. The LDF is a weak intermolecular force arising from quantum-induced instantaneous polarization multipoles in molecules. They can therefore act between molecules without permanent multipole moments.
