Organic I: Struct & Reactivity
Course Description
Organic Chemistry I: Structure and Reactivity
In this course we will provide students with an introduction to the structure and reactivity of organic molecules sufficient to continue directly to the study of biochemistry (CHEM 0322). Topics covered will include models of chemical bonding, acid-base relationships, three-dimensional molecular structure (conformations and stereochemistry), reaction mechanisms and energy diagrams, substitution and elimination reactions, carbonyl reactions (additions, reductions, interconversions, and alpha-reactivity), and the fundamentals of biological molecules (carbohydrates, DNA, and RNA). Laboratory experiments will relate to purification techniques (recrystallization, distillation, extraction, and chromatography), as well as microscale organic reactions that complement the lecture material. (CHEM 0104 or CHEM 0105 or CHEM 0107) 3 hrs. lect., 3 hrs. lab. (formerly CHEM 0203)

Organic II: Synthesis & Spect.
Course Description
Organic Chemistry II: Synthesis and Spectroscopy
In this course students will explore how organic molecules are made and their structures are identified. The study of organic reactions will continue from CHEM 0205 with radical reactions, alkene and alkyne additions, aromatic reactions, oxidations, reductions, and additional carbonyl reactions. Emphasis will be placed on using reactions in sequences to synthesize larger and more complex molecules. The theory and practice of mass spectrometry and UV-Vis, IR, and NMR spectroscopy will be studied as a means to elucidate the exact structures of organic molecules. Laboratory experiments will focus on synthetic techniques that complement the lecture material and the identification of complex unknowns via spectrometry and spectroscopic techniques. (CHEM 0203 or CHEM 0205) 3 hrs. lect., 3 hrs. lab. (formerly CHEM 0204)
