Ch. 9 - Polarity, Intermolecular Forces, Kinetic Molecular Theory and Gases

Question 1

What is the Kinetic Molecular Theory?

Answer 1

1) Molecules are in constant random motion

2) Molecules move at different speeds. The average speed is proportional to temperature.

Question 2

What are the six types of intermolecular forces?

Answer 2

1) Ion - ion
2) ion - dipole
3) ion - induced dipole
4) dipole - dipole
5) dipole - induced dipole
6) induced dipole - induced dipole (LDF)

Question 3

Hydrogen bonding is an example of which type of intermolecular force?

Answer 3

Dipole - dipole

Question 4

Which elements form strong bonds with hydrogen?

Answer 4

F, O, and N.

Question 5

What is an induced dipole?

Answer 5

A polar molecule that closely approaches a non-polar molecule which causes the non-polar molecule to have a temporary dipole.

Question 6

What are the properties of an ideal gas?

Answer 6

1) The distance between particles is much larger than the size of the particles
2) Particles are in constant motion
3) Particles do not interact except when they collide.
4) Collisions are elastic (no energy is lost)
5) The particles move at different speeds.
