Web8 apr. 2024 · London dispersion force, named after Fritz London, is a component of Waals force. It occurs as an attraction within various molecules as a result of immediate polarization. However, some non-polar ones also experience this force. Factors Affecting the Strength of Van Der Waal. The factors affecting Van Der Waals forces are as follows: Web16 aug. 2024 · In helium, the London dispersion forces are particularly weak. This is shown by the fact that it has a very low boiling point (-270°C). This is the temperature at which its molecules will have enough strength to stick together and condense into a liquid.
