Question

What are Dispersion Forces?

Expert Solution

Step 1

The distribution of electrons in an atom or molecules are not uniform as a result slightly negative charge appear on one side of atom whereas the other region opposite to it becomes positive due to deficiency of electrons. This positive-negative centers keeps on changing hence it is called instantaneous dipole.

The negative end of one atom/molecule attracts the other side of other atom/molecule. This results in the dinding force called dispersion forces.
