Module 2 Intro

Module 2—Chemical Compounds

Module Summary

As you worked through this module, you kept the following questions in mind. Did your studies help you answer these questions?

• What are the roles of modelling, evidence, and theory in explaining and understanding the structure, bonding, and properties of molecular compounds?
  
  
• Why do substances have different melting and boiling points?
  
  
• How can principles of bonding in matter be used to develop unique materials?

Throughout your study in this module you learned about many technologies involving molecular compounds and about how the bonding of these compounds can be used to make materials useful to you. Chemical principles you studied include electronegativity, bond polarity, VSEPR theory, stereochemistry, molecular polarity, and different types of intermolecular bonding forces including London, dipole-dipole, and hydrogen bonds.

Module Assessment

The assessment for this module consists of four lesson assignments. As you completed these assignments, you have also considered some of the larger questions regarding the application of principles of bonding to technologies used throughout history. Your work on these assignments will prepare you to complete the Unit Assessment exercise.
