Van der Waals interactions are weak and only occur when atoms/molecules are very close together.

Cohesion: attraction between molecules of the same substance.

Polar molecule: opposite ends of the molecule have opposite charges. (e.g. water is a polar molecule)

6. Which of the following is INCORRECT?
