Chemistry Lab 10- Intermolecular Interactions

Question 1

Which is a stronger bond? Inter or intramolecular bonds?

Answer 1

Intramolecular bonds are stronger.

Question 2

What is the difference between inter and intramolecular bonds?

Answer 2

Intramolecular means bonds within a molecule

Intermolecular means bonds between molecules

Question 3

What are the three types of intermolecular bonds? From weeks to strongest?

Answer 3

Dispersion- no charge separation
Dipole- partial charge separation
Ionic- complete charge separation

Question 4

Molecules that interact through dispersion bonds tend to be?

Answer 4

Gases/ low boiling point liquids

Question 5

Molecules that interact through dipole bonds tend to be?

Answer 5

Liquids/ low melting point solids

Question 6

Molecules that interact through ionic bonds tend to be?

Answer 6

Solid at room temperature

Question 7

Induced dipole moment

Answer 7

The tiny moment in time (10 to the -15 seconds) when one side of a molecule is more negative than the other.

Question 8

What can happen between two molecules during a induces dipole moment?

Answer 8

The molecule with the polarized charges can cause other molecules to become polarized and they bond at the points where their opposite poles interact.
