Question

1. What are van der Waals’ forces? 

2. Which are the different types of van der Waals’ forces? 

3. Arrange the van der Waal’s forces in the increasing order of their strength.

Answer 1

1. The attractive intermolecular forces are known as van der Waals’ forces. 

2. Dispersion forces/London forces, Dipole-Dipole forces, Dipole-Induced dipole forces and Hydrogen bonding.

3. Dispersion forces/London forces < Dipole-Induced dipole forces < Dipole-Dipole forces < Hydrogen bonding.
