What is the van der Waals force?

What is the van der Waals force?

• A. An electrical repulsion between particles
• B. An attraction between charged particles only
• C. An attraction between all particles in nature
• D. A gravitational force acting on particles

Answer: (C)

The van der Waals force refers to a type of attraction that occurs between all types of particles, including neutral atoms and molecules. This attractive force arises from fluctuations in electron distributions within atoms and molecules, leading to temporary dipoles that can induce further dipoles in nearby particles. As a result, even non-polar molecules experience van der Waals forces, making them fundamental interactions that are present in various states of matter. These forces play a significant role in many physical and chemical processes, such as the properties of gases, the behavior of colloids, and the interactions between biomolecules. Understanding van der Waals forces is essential in fields like chemistry, biology, and material science since they contribute to phenomena like adhesion, molecular binding, and the overall stability of structures at the molecular level.
