Which is the weakest intermolecular force, considered as the Van der Waals force, often found in halogens, noble gases and other non-polar molecules?
- ALondon dispersion forces
- BIon-dipole forces
- CDipole- induced dipole forces
- DDipole - dipole forces
Solution & Step-by-step Explanation
London dispersion forces (or simply dispersion forces) are the weakest intermolecular forces. They are temporary attractive forces that result when the electrons in two adjacent atoms or non-polar molecules occupy positions that make the atoms form temporary dipoles. These forces are highly significant in non-polar species like noble gases (He, Ne, etc.) and homonuclear diatomic halogens (F
