Detailed explanation-1: -These forces are named after the German physicist Fritz London and are also known as instantaneous dipole – induced dipole forces.
Detailed explanation-2: -Taken individually van-der-Waals interactions are weak attractions between molecules that are in close proximity to each other. They are also known as London dispersion forces.
Detailed explanation-3: -The term that accounts for intermolecular force in Van der Waals equation is: RT. V-b. (P + a/V2 )
Detailed explanation-4: -Van der Waals forces are weak electrostatic forces that attract neutral molecules to one another. Particles in liquid or air vibrate and move constantly. Thus, they collide with other particles, including the media’s particles such as water molecules-the process known as Brownian motion (Figure 50).
Detailed explanation-5: -Van der Waals forces are a category of intermolecular forces that includes London dispersion and dipole-dipole interactions. Some sources also consider hydrogen bonding to be a Van der Waals force. London dispersion forces are present between all molecules.
