Question

Which of the following factors is responsible for van der Waals forces ?

• A. Instantaneous dipole-induced dipole interaction
• B. Dipole-induced dipole interaction and ion-induced dipole interaction
• C. Dipole-dipole interaction and ion-induced dipole interaction
• D. All of these.

Answer 1

The correct option is D All of these.

Van der waals forces include ion-dipole attraction, dipole-dipole attraction, ion-induced dipole attraction, dipole-induced dipole attraction, Instantaneous dipole- Instantaneous induced dipole attraction.
Hence, the correct answer is option (d).
