Which of the following is a false statement about dispersion forces? View Available Hint (s) Which of the following is a false statement about dispersion forces? Dispersion forces are the result of fluctuations in the electron distribution within molecules or atoms. Dispersion forces are present in all atoms and molecules. Dispersion forces result from the formation of instantaneous dipoles in a molecule or atom. Dispersion forces always have a greater magnitude in molecules with a greater molar mass. Dispersion force magnitude depends on the amount of surface area available for interactions.

    Dispersion forces are also known as London dispersion forces. It is the weakest force. Also, it is the part of the Van der Waals forces.

    (1) This force is exhibited by all atoms and molecules.

    (2) These forces are the result of the fluctuations in the electron distribution within molecules or atoms. Due to these fluctuations, the electric field is created. The magnitude of this force is explained in terms of Hamaker constant 'A'.

    (3) Dispersion forces result from the formation of instantaneous dipoles in a molecule or atom. When electrons are more concentrated in a place, instantaneous dipoles formed.

    (4) Dispersion force magnitude depends on the amount of surface area available for interactions. If the area increases, the size of the atom also increase. As a result, stronger dispersion forces.

    So, the false statement is "Dispersion forces always have a greater magnitude in molecules with a greater molar mass".
