3.6 structure of simple molecules

Question 1

Are the melting and boiling points of simple molecules high or low?

Answer 1

Substances made of simple molecules have low melting points and boiling points

Question 2

The forces between a simple molecules are what?

Answer 2

The force between simple molecules a week. These weak intermolecular forces explain why substances made of simple molecules have low melting points and boiling points.

Question 3

Simple molecules have what charge?

Answer 3

Simple molecules have no overall charge, so they cannot carry electrical charge. Therefore, substances made of simple molecules do not conduct electricity.

Question 4

What are models used for?

Answer 4

Models are used to help understand bonding but each model has its limitations in representing reality

Question 5

What does intermolecular forces mean?

Answer 5

The attraction between the individual molecules in a covalently bonded substance

Question 6

What are polymers?

Answer 6

A substance made from very large molecules made up of many repeating units
