How can Van der Waals forces be used to determine relative boiling point?
1 Answer
The stronger the intermolecular forces between the liquid molecules of a given substance, the higher its boiling point.
Explanation:
The stronger the intermolecular forces between the liquid molecules of a given substance, the higher its boiling point.
Van der Waals forces ( also called London Dispersion Forces
Note that the polarizability increases with the surface area, therefore, for longer chains the surface area of contact increases and so the Van der Waals forces.
For example, the boiling point of pentane
