Associate in Science Instruction in Chemistry/Biochemistry
Steve Oster obtained a B.A. in history from Nyack College in 1990, and a B.S. in Chemistry from York College in 1998. He earned his Ph.D. from the University of Rochester in 2003, and taught for one year at Whitworth College in Spokane, Washington, before joining Middlebury College in 2004.

CHEM 0203 / CHEM 0241 - Organic I: Struct & Reactivity ▹
Organic Chemistry I: Structure and Reactivity
This course will provide students with an introduction to the structure and reactivity of organic molecules sufficient to continue directly to 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 include purification techniques (recrystallization, distillation, extraction, and chromatography) as well as microscale organic reactions that complement the lecture portion of the course. (CHEM 0104 or CHEM 0107) 3 hrs. lect., 3 hrs. lab, 1 hr. prelab.

CHEM 0204 / CHEM 0242 - Organic II: Synthesis & Spect ▹
Organic Chemistry II: Synthesis and Spectroscopy
In this course we will explore the ways that organic molecules are made and their structures identified. The study of organic reactions will continue from CHEM 0203 with radical reactions, alkene and alkyne additions, aromatic reactions, oxidations and reductions, and additional carbonyl reactions. Emphasis in this course 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 portion of the course and the identification of complex unknowns via GC-MS, IR, and NMR. (CHEM 0203) 3 hrs. lect., 3 hrs. lab, 1 hr. prelab.
