Chemistry 2003 JAMB Past Questions - Question 12: The weakest attractive force that can be observed between two molecules is

Correct Answer

D

Explanation

 The weakest attractive force that can be observed between two molecules is Van der Waals forces. Van der Waals forces are relatively weak compared to ionic and covalent bonds. Ionic bonds involve the transfer of electrons between atoms, resulting in the formation of positive and negative ions that are held together by electrostatic forces. Covalent bonds involve the sharing of electrons between atoms.

Van der Waals forces, on the other hand, are interactions between temporary dipoles in molecules. These forces can be further divided into London dispersion forces, dipole-dipole interactions, and hydrogen bonding. London dispersion forces are the weakest among them and arise from the temporary fluctuations in electron distribution, leading to the creation of temporary dipoles in adjacent molecules.
