Attractive forces between polar elements

Question 22

How do Van der waals work

Answer 22

In a non polar molecule the electron charge cloud moves forming an instantaneous dipole
As this dipole approaches a non polar molecule there is repulsion causing the molecules charges to shift forming an induced dipole and then there is an attraction which is the imf
