5.3 Polarity & Intermolecular Attractions

Question 1

What makes a molecule polar?

Answer 1

It must have a polar covalent bond and it must have an asymmetrical pull on electrons.

Question 2

How do you determine molecule polarity based on structure?

Answer 2

Draw in the dipoles to see if the electrons are pulled equally or not.

Question 3

What are the three types of intermolecular attractions?

Answer 3

London dispersion, dipole-dipole, and hydrogen bonds.

Question 4

What are the strongest intermolecular attractions?

Answer 4

Hydrogen bonds

Question 5

What are the weakest intermolecular attractions?

Answer 5

London dispersion

Question 6

What molecules can do London dispersion?

Answer 6

Any molecule

Question 7

What molecules can do dipole-dipole?

Answer 7

Any molecule that is polar.

Question 8

What molecules can do hydrogen bonds?

Answer 8

Any polar molecule that has O-H, N-H, or F-H bonds.
