AP Chemistry · Unit 2: Compound Structure and Properties
2.1 Types of Chemical Bonds
In short
You are expected to qualitatively understand electronegativity trends using the shell model and Coulomb's law. The curriculum emphasizes that bonding is a continuum rather than distinct categories; all polar bonds have some ionic character. You must know that C-H bonds are effectively nonpolar.

What else do you need to know about Types of Chemical Bonds?
Furthermore, you should understand that electronegativity difference alone does not dictate bond type; macroscopic properties are the best way to characterize bonding. Metallic bonding must be understood as a system of delocalized valence electrons.
How is Types of Chemical Bonds tested on the exam?
This topic is assessed primarily through the science practice of Argumentation (Make a scientific claim). You may be asked to explain the connection between electronegativity, the type of bond formed, and the macroscopic properties of a substance. A common expectation is to provide explanations across scales (particulate to macroscopic) rather than just stating chemical theories.
