Ch 13: General Science: Types of Chemical Reactions

About This Chapter

Arizona has replaced the AEPA General Science exam with the NES General Science exam. As you get ready for the test, use this chapter to heighten your knowledge of chemical bonds, chemical reactions and their properties.

AEPA General Science: Types of Chemical Reactions - Chapter Summary

Review this chapter about the types of chemical bonds and reactions as well as their properties. Start by watching this series of short lesson videos, taught by our professional instructors, that will help you prepare for exam questions about:

  • Bond polarity and Ionic character of covalent bonds
  • The effects of molecule shape and the VSEPR theory
  • Strong intermolecular forces of hydrogen bonding
  • Weak intermolecular forces
  • Molecular orbital theory
  • Metallic bonding
  • Organic and inorganic macromolecules and intramolecular bonding
  • Types of organic molecules

Since these lesson videos can be watched on a smartphone, tablet or computer, they offer a versatile way of reviewing the different types of chemical bonds and reactions. Transcripts contain important words in bold print and they can be read through at a pace that's comfortable for you. Ask our experts via the dashboard feature if you have questions about chemical reactions.

AEPA General Science: Types of Chemical Reactions Chapter Objectives

The objective of the AEPA General Science exam is to determine whether prospective science teachers have the knowledge necessary to qualify for certification. This computer-based exam has a three-hour time limit, and it will require you to answer150 multiple-choice questions.Thirty-seven percent of the material in this exam will fall under the Physical Science content domain. Use this chapter to prepare for the questions by reviewing different bonds and the energy between them.

Covalent Bonds: Predicting Bond Polarity and Ionic Character

1. Covalent Bonds: Predicting Bond Polarity and Ionic Character

Learn about covalent bonds and their two types: nonpolar covalent bonds and polar covalent bonds. Discover how to predict the type of bond that will form based on the periodic table. Learn what ionic character means and how to determine it.

VSEPR Theory & Molecule Shapes

2. VSEPR Theory & Molecule Shapes

In this lesson, you'll learn about the VSEPR theory and how it can be used to explain molecule shapes. Then, learn how to predict the shape of a molecule by applying the VSEPR theory to the Lewis dot structure.

Hydrogen Bonding, Dipole-Dipole & Ion-Dipole Forces: Strong Intermolecular Forces

3. Hydrogen Bonding, Dipole-Dipole & Ion-Dipole Forces: Strong Intermolecular Forces

Learn about intermolecular vs. intramolecular forces. Learn the different intermolecular bonds (including hydrogen bonding and dipole-dipole and ion-dipole forces), their strengths, and their effects on properties, such as boiling and melting points, solubility, and evaporation.

London Dispersion Forces (Van Der Waals Forces): Weak Intermolecular Forces

4. London Dispersion Forces (Van Der Waals Forces): Weak Intermolecular Forces

Learn how London dispersion forces are created and what effect they have on properties such as boiling and melting points. Discover this weak intermolecular force and how it is one of the Van der Waals forces.

Using Orbital Hybridization and Valence Bond Theory to Predict Molecular Shape

5. Using Orbital Hybridization and Valence Bond Theory to Predict Molecular Shape

You'll learn how to explain how shapes of molecules can be predicted using valence bond theory and hybridization. When finished, you'll understand the difference between sigma and pi bonds and how the VSEPR theory, along with the hybridization theory, helps predict the shape of a molecule.

Molecular Orbital Theory: Tutorial and Diagrams

6. Molecular Orbital Theory: Tutorial and Diagrams

Learn how to sketch the overlap of orbitals to form sigma and pi bonds. Use the molecular orbital theory to determine bond order. Discover how bond order affects bond strength and bond energy.

Metallic Bonding: The Electron-Sea Model & Why Metals Are Good Electrical Conductors

7. Metallic Bonding: The Electron-Sea Model & Why Metals Are Good Electrical Conductors

Learn why metallic bonding is called the electron sea model. Discover why metals bond the way they do and why they are shiny, malleable and conduct electricity well.

Intramolecular Bonding and Identification of Organic and Inorganic Macromolecules

8. Intramolecular Bonding and Identification of Organic and Inorganic Macromolecules

Understand what a macromolecule is and be able to identify both organic and inorganic macromolecules. Organic molecules include proteins, lipids, carbohydrates and nucleic acids.

Organic Molecules: Alkanes, Alkenes, Aromatic Hydrocarbons and Isomers

9. Organic Molecules: Alkanes, Alkenes, Aromatic Hydrocarbons and Isomers

Learn more about carbon and hydrogen and see how these atoms come together to form distinct molecules. Also, study the difference between saturated and unsaturated molecules.

Functional Groups in Organic Molecules

10. Functional Groups in Organic Molecules

Learn what an organic compound is and how their functional groups affect them. Identify the different types of functional groups including alcohols, alkyl halides, ketones, aldehydes, ethers, carboxylic acids and esters.
