Ch 36: Understanding Chemical Bonds

About This Chapter

This chapter is all about the forces, structures, and processes involved with chemical bonds. You'll learn to define key terms, differentiate between different forms of bonds, and much more.

Understanding Chemical Bonds - Chapter Summary

This chapter examines numerous principles, models, and variations to know when studying chemical bonds. You'll review topics such as metallic bonding, the octet rule, ionic bonds, and more. A full breakdown of topics covered includes:

  • Polar and non-polar covalent bonds
  • Lewis structures
  • Hydrogen bonding
  • Dipole-dipole and ion-dipole forces
  • London dispersion forces
  • Orbital hybridization and valence bond theory
  • Intramolecular bonding
  • Identifying organic and inorganic macromolecules

These lessons let you choose between a video or transcript of the material, depending on your studying preference. The timeline feature enables video watchers to jump around main points of the lesson, while the bolded words throughout the transcripts allow readers to easily spot key terms and topics.

The Octet Rule and Lewis Structures of Atoms

1. The Octet Rule and Lewis Structures of Atoms

Learn the octet rule and how it applies to electron energy levels. Identify valence electrons and learn how to determine them by looking at the periodic table. Also, discover how they pertain to the octet rule. Learn how to draw the Lewis diagram of an atom, and understand how it provides clues to chemical bonding.

Ionic Bonds: Definitions and Examples

2. Ionic Bonds: Definitions and Examples

Did you know that when atoms stick together to form molecules, they gain and lose electrons, making them negatively or positively charged? In this lesson, you will learn how cations and anions form one type of chemical bond called an ionic bond.

Polar and Nonpolar Covalent Bonds: Definitions and Examples

3. Polar and Nonpolar Covalent Bonds: Definitions and Examples

Did you know that some types of chemical bonds behave similarly to the way that children play with toys? In this lesson, you will learn about two types of bonds called polar and nonpolar covalent bonds.

Lewis Structures: Single, Double & Triple Bonds

4. Lewis Structures: Single, Double & Triple Bonds

Review what a Lewis dot diagram is and discover how to draw a Lewis dot structural formula for compounds. Learn how to represent single, double and triple bonds with lines instead of dots. Also, learn how compounds arrange themselves.

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

5. 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

6. 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

7. 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.

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

8. 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

9. 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.
