What dictates London Dispersion? I’m unsure on this.

every molecule has london dispersion forces

Any molecule can induce a dipole on another molecule. So, any molecule can have these dispersion forces.

London Dispersion forces can happen in all molecules because of the fluctuating electron distribution on atoms results in fluctuating dipoles. These interactions are very weak and are easily broken.

London dispersion is dictated by the proximity of electrons in two adjacent atoms occupy positions that make the atoms form temporary dipoles. This force induces a dipole-dipole attraction and is what causes condensation into liquids and freezing into solids.

London dispersion is the weakest type of intermolecular forces.

London dispersion forces happen because electrons moving can induce dipole forces due to attraction.

Every molecule has London dispersion forces which are created by momentary dipoles. Because they add up, larger molecules have stronger dispersion forces than smaller molecules.

All molecules have london dispersion forces due to the randomized dispersion of electrons at a singular moment which can strengthen the dipole towards a certain direction due an increased density of electrons.

All molecules have LD forces that interact with other molecules

London dispersion is another name for Van der Waals forces, which is essentially really weak and temporary polarizations occurring due to the random movement of electrons in a molecule. It is the weakest intermolecular force and may occur on all molecules.

LDF is the weakest of the intermolecular forces. LDF occurs when electrons in two adjacent atoms form temporary dipoles.

Ah this one is the easiest :) From my understanding, all molecules will have London dispersion as an intermolecular force.
