Question

Which of the following are 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. Small size of molecule

Answer 1

Answer: (A), (B), (C)

The correct options are
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

Van der Waals forces are independent of the size of the molecules because they originate from the electrostatic force. The dipole-dipole interactions lead to Vander Waal forces.
