Question

Which one of the following is the correct order of interactions?

• A. Covalent < hydrogen bonding < van der Waals' < dipole-dipole
• B. van der Waals' < hydrogen bonding < dipole < covalent
• C. van der Waals' < dipole-dipole < hydrogen bonding < covalent
• D. Dipole-dipole < van der Waals' < hydrogen bonding < covalent

Answer 1

Answer: (B)

The van der Waals forces are weakest forces and covalent bond is strongest, so the order of interactions is van der Waals $<$ H-bonding $<$ dipole-dipole $<$ covalent.
