[P + a(n/V)2] (V - nb) = nRT
As you see this is a correction method for gasses other than ideal. Gasses at high pressure and high/low temperature. The ideal gas equation makes assumptions that are not always applicable to real word conditions as to gasses.
Yes, methane (CH4) would exhibit van der Waals forces, specifically London dispersion forces. These forces arise from the temporary shifting of electron distributions, which induces a temporary dipole in neighboring molecules and leads to attraction between them.
There are Four Forces: Hydrogen Bonding Dipole-Dipole London Dispersion Forces Vander Waals Forces
One example of a van der Waals solid is sulfur. In its solid form, sulfur molecules are held together by weak van der Waals forces, resulting in a relatively low melting and boiling point compared to other solids.
A Gecko cannot stick to Polytetrafluoroethylene (a.k.a. Teflon) due to the plastics resistance to Van Der Waals forces The oil will disrupt the vander waals force that allows a gecko to climb. Plastic is made from oil. Why do gecko's feet stick so well? The the vander waals force unique form by seta, tiny hairs that have spatula shaped tips. Water increase this power and oil will stop it. I saw a gecko slip on a human leg and couldn't believe it. Must of had oily skin?
Chlorine has a greater value for the van der Waals constant b than ethane. This is because chlorine has a larger molecular size and therefore requires more space for its molecules to move freely, resulting in a larger value of b.
Van der Waals forces, which are weak attractive forces between molecules, can increase the boiling point of a substance. This is because the attraction between molecules makes it more difficult for them to escape into the gas phase. Therefore, substances with stronger van der Waals forces typically have higher boiling points.
The common force is only the Vander-Waal's force.
Peter Waals died in 1937.
Vander Waals constant 'a' represents the attraction between gas molecules, while constant 'b' represents the volume occupied by the gas molecules. 'a' is related to the cohesive forces between molecules, while 'b' is related to the excluded volume due to the size of the molecules. These constants help account for deviations from ideal gas behavior in real gases.

The Van de Waals Force test is a physical chemistry term. The Van de Vaals force (or interaction) was named for the Dutch scientist Johannes Diderik van de Waals.
