Van der Waals Interactions

Question 1

What is a Van der Waal force?

Answer 1

The attraction between temporary induced dipoles.

Question 2

True or False: Van der Waal forces exist between all atoms and molecules?

Answer 2

True

Question 3

True or False: Van der Waal forces are the only forces of attraction between atoms and non-polar molecules.

Answer 3

True

Question 4

True or False: With Van der Waal’s, strength increases as the mass and number of electrons in a molecule increases.

Answer 4

True

Question 5

Even though Van der Waal’s are weak, they contribute to forces how?

Answer 5

They contribute significantly to the attractive forces between large molecules as they act over large surface areas.
