Answer Details
The weakest attractive force that can be observed between two molecules is van der Waals force. Van der Waals force is a weak electrostatic attraction that exists between the positive and negative charges of two adjacent molecules. This force arises due to the fluctuations in the electron cloud around the atoms in the molecule. While ionic, covalent, and coordinate covalent bonds involve the transfer or sharing of electrons between atoms to form a strong attraction, van der Waals force is a relatively weak attraction between two molecules.
