Objectives

 

Purpose:

To relate the electron configuration of carbon to the bonding in organic molecules and to survey the nomenclature, molecular features and simple chemical reactions of alkenes, alkynes, and aromatic compounds.

 

Objectives: You have completed this lesson when you can:

1. Describe what is meant by "hybrid orbitals" and "hybridization."

2. Relate the type of hybridization of a particular carbon atom to the geometry of the atoms bonded to that carbon atom.

3. Describe what is meant by sigma and pi bonding and identify such bonding in structural formulas.

4. Describe how the lack of rotation around double and triple bonds can affect the shape of molecules.

5. Give a definition of geometric (cis-/trans-) isomerism.

6. Recognize examples of geometric isomerism and identify the cis- and trans- isomers.

7. Describe the structural features (including hybridization and bonding) of the groups of organic compounds called the alkenes, alkynes, and aromatic compounds.

8. Give and recognize examples of alkenes, alkynes, and aromatic compounds.

9. Write out the IUPAC name of a simple alkene, alkyne, or aromatic compound given the structural formula.

10. Write the structural formula of a simple alkene, alkyne, or aromatic compound given the IUPAC name.

11. Explain why alkenes, alkynes, and aromatic compounds are insoluble in water.

12. Relate molecular size and weight to melting and boiling points of alkenes, alkynes, and aromatic compounds.

13. Describe what happens in an addition reaction. Identify, recognize, and give examples of such.

14. Describe what happens in a substitution reaction. Identify, recognize, and give examples of such.

15. Describe what happens in the polymerization reaction of an alkene. Identify, recognize, and give examples of such.

16. Given the name or structural formula of a monomer, name the polymer that can be derived from it, write the structural formula for a segment of that polymer, and write an equation for the polymerization reaction.

17. Given the structural formula for a section of a polymer, find the repeating unit, name the monomer from which it was derived, and name the polymer.

18. Use appropriate chemical tests to detect the presence of the following functional groups in the lab: double or triple bonds and benzene rings.

19. Use infrared spectra to help identify the following types of organic compounds: alkenes, alkynes, and aromatic compounds.
