Section: Module 4: Lesson 3: Aromaticity and the Hückel 4n + 2 Rule | Organic Chemistry 2 | NextGenU.org

  • Student Learning Outcomes:
    Upon completion of this module, students you will be able to:
    • Define aromaticity in terms of the Hückel 4n + 2 rule and determine whether or not a given polyunsaturated cyclic hydrocarbon should exhibit aromatic properties.
    • Describe the difference in properties between an aromatic hydrocarbon, such as benzene, and a non-aromatic polyunsaturated cyclic hydrocarbon, such as cyclobutadiene or cyclooctatetraene.
    • Draw molecular orbital diagrams for aromatic species, such as benzene, the cyclopentadienyl anion, and pyridine, and compare these diagrams with those obtained for non-aromatic species, such as cyclobutadiene and the cyclopentadienyl cation.
    Approximate time required for the readings for this lesson (at 144 words/minute): 39 minutes.
