      No such scene. Van der waals forces are intermolecular forces and exist between all molecules. Then, there are types of van den waals forces which are dominant in some particular molecules.

    • @aena_
      @aena_ 3 года назад

      Van der waals forces and London Dispersion Forces are two different terms. Actually, LDF is a type of van der waals forces. LDF is present in all types of molecules whether polar or non polar. This makes sense that in chlorine, LDF is more dominant

    All of your videos are amazing; thanks for sharing!
    I always had trouble on deciding whether I needed to use the term “Van der Waals” or “London dispersion”. I think many times they are used synonymously, but technically, I think that London dispersion forces (LDFs) refer only to the attraction between a temporary dipole and a dipole it induces. LDF is a type of Van der Waals force, however VdW also encompasses permanent dipole-induced dipole and permanent dipole-permanent dipole interactions.

    • @HenryFabianGT

    • @MDMAx
      @MDMAx Год назад

      Larger molar mass, or more electrons = more electric charge.
      More electric charge = more random fluctuations.
      More random fluctuations = larger probability to create a random dipole a.k.a. induce a Van der Waals force between neighboring atoms
