Which is the weakest intermolecular force, considered as the Van der Waals force, often found in halogens, noble gases and other non-polar molecules?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. London dispersion forces.
- London dispersion forces is the weakest intermolecular force, considered as the Van der Waals force, often found in halogens, noble gases and other non-polar molecules.
- London dispersion forces originate from momentary shifts in electron distribution, forming temporary dipoles.
- These dipoles, in turn, induce dipoles in nearby atoms or molecules, resulting in a weak attractive force.
- Such interactions are especially common among halogens, noble gases, and other non-polar substances.
