Question

The weakest interaction among the following is _____.

• A. Metallic
• B. Ionic
• C. Van der Waal
• D. Covalent

Answer 1

The correct option is C

Van der Waal

Ionic bonds arise from electrostatic forces.
Covalent bonds are result of $e^{-}$ sharing.
Metallic bonds happen because of $e^{-}$ delocalisation.
Van der Waals' force is because of dipole-dipole interactions, which are observed to be very weak when compared to the others.
