(a) Interpretation: The substance with larger dispersion forces needs to be determined. C 8 H 18 , Octane, C 2 H 6 and Ethane Concept introduction: Dispersion forces sometimes are known as London Forces, induced-dipole forces, van der Waals forces or London Dispersion forces. They are induced-dipole forces which develop from variations within the electron’s arrangement around the molecule. Even molecule which is non-polar will not contain the perfect dispersal of charge for every moment of time.
