The material included in this area of the FTCE Chemistry course is meant to steer you in the direction of the kinds of questions you will be answering during the FTCE exam. Self-assessment quizzes are available for you to evaluate your progress and determine whether there are any concepts to which you need to pay special attention; if so, a team of expert instructors is available to answer any of your questions that may come up during your studies.
1. Overview of Chemical Bonds
Learn about the most common kinds of chemical bonds: ionic, covalent, polar covalent, and metallic. Discover how they form and why they hold together. Take a quiz and see how much knowledge you've held onto.
2. 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.
3. Lewis Dot Structures
Although drawing dots around elements sounds pretty straight forward, Lewis dots are a little more complicated. This lesson will explain how to draw Lewis dots for single, double, and triple bonds, as well as polyatomic ions.
4. Ions: Predicting Formation, Charge, and Formulas of Ions
Learn how ions are formed using the octet rule. Use the periodic table to predict the charge an atom will have when it becomes an ion. Learn whether an ion is a cation or anion and how to write the formula depending on what charge the ion has.
5. What Are Ionic Compounds? - Definition, Examples & Reactions
Ionic compounds are a common, yet special type of chemical compound. In this video lesson, you will learn about their formation and structure and see examples of compounds formed by ions.
6. Writing Ionic Compound Formulas: Binary & Polyatomic Compounds
In this lesson, you will learn how to write the chemical formulas for both binary ionic compounds and polyatomic ionic compounds when you are given only the name of the compound. You will see that it is actually quite simple when you learn the steps described in this lesson.
7. Covalent Compounds: Properties, Naming & Formation
Learn about covalent bonds, how covalent compounds are formed and the properties inherent to covalent compounds, such as low melting and boiling points, in this lesson. Also, learn what rules to follow to name simple covalent compounds.
8. 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.
9. 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.
10. 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.
11. 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.
12. 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.
13. 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.
14. 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.
15. 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.
16. 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.
17. 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.
