Final answer:
The name of the intermolecular force caused by an instantaneous dipole in the particles is London dispersion force.
Step-by-step explanation:
The name of the intermolecular force caused by an instantaneous dipole in the particles is London dispersion force. This force is also known as the Van der Waals force and is the weakest intermolecular force. It occurs between all particles, including atoms and molecules, and is caused by temporary fluctuations in electron distribution that create temporary dipoles.
London dispersion forces are responsible for the cohesion of nonpolar molecules and are essential for the existence of gases, liquids, and solids. These forces increase with the size of the atoms or molecules involved and with the surface area of contact between them.
