Question 1

What are the three intermolecular attractions?

Answer 1

London Dispersion, Dipole-Dipole, Hydrogen Bond.

Question 2

What is London Dispersion(LD)?

Answer 2

Temporary attraction between two molecules. Temporary dipoles are created.

Question 3

What is Dipole - Dipole?

Answer 3

The larger the partial charges = the stronger the attraction. Opposite ends connect with dipoles forming.

Question 4

What is a Hydrogen Bond?

Answer 4

The strongest type of attraction. It is formed when two molecules have: O-H, N-H, and F-H bonds.

Question 5

Rank the attractions from weakest to strongest.

Answer 5

LD, Dipole-Dipole, Hydrogen Bond.

Question 6

What type of molecules can form LD?

Answer 6

All molecules can.

Question 7

What can form Hydrogen bonds?

Answer 7

Only polar molecules.

Question 8
