Detailed Solution for Chemical Bonding - 1 - Question 11

To determine the correct order of interactions based on their strength, let’s examine each type:

Van der Waals’ Forces: These are the weakest interactions and include London dispersion forces. They are generally weaker than dipole-dipole interactions, hydrogen bonds, and covalent bonds.
Dipole-Dipole Interactions: These are stronger than van der Waals’ forces but weaker than hydrogen bonds and covalent bonds.
Hydrogen Bonding: Hydrogen bonds are typically stronger than dipole-dipole interactions and van der Waals’ forces but weaker than covalent bonds.
Covalent Bonds: Covalent bonds are strong chemical bonds that involve sharing electrons between atoms. They are much stronger than hydrogen bonds, dipole-dipole interactions, and van der Waals’ forces.

Given this order of strength:

Answer: (c) Van der Waals’ < Dipole-Dipole < Hydrogen Bonding < Covalent
