What intramuscular force attracts two non polar molecules to each other?

The intramuscular force that attracts two nonpolar molecules to each other is known as London dispersion forces, a type of van der Waals force. These forces arise due to temporary fluctuations in electron distribution within molecules, creating instantaneous dipoles that induce dipoles in neighboring molecules. Although these interactions are relatively weak compared to other types of chemical bonds, they can accumulate in large numbers, leading to significant attraction between nonpolar molecules.
