Van der Waals force include dipole-dipole, dipole-induced dipole, induced dipole-induced dipole interactions according to my organic chemistry book, physical chemistry book and wikipedia👍. But what is Van der Waals force for the MCAT? Is it the same as aforesaid or is it strictly dipole-induced dipole interaction (since people would think induced dipole-induced dipole is only called London dispersion). And is there something called "dipole force"?
