Teaching this semester

CHEM 1092. Introductory Chemistry and Quantitative Reasoning II, L1

The second course in a two-semester introductory college chemistry sequence that follows Chemistry 1091. Incorporates additional instruction focused on developing quantitative reasoning and problem-solving skills in the context of learning chemistry. Topics include gases, properties of solutions, thermodynamics and thermochemistry, kinetics, equilibrium, electrochemistry, and acid-base chemistry. Three hours of lecture, mandatory one-hour problem-solving session, and four hours of laboratory work per week.

CHEM 1102. Introductory Chemistry II, L1

The second course in a two-semester introductory college chemistry sequence. Introduction to chemical bonding and intermolecular forces, characterization of chemical systems at equilibrium and spontaneous processes, the rates of chemical reactions, and special topics. Lectures, review sessions, and four hours of laboratory work per week. Students who have taken Chemistry 1109 may not take Chemistry 1102 for credit.

CHEM 1109. General Chemistry, L1

A one-semester introductory chemistry course. Introduction to models of atomic structure, chemical bonding, and intermolecular forces; characterization of chemical systems at equilibrium and spontaneous processes; the rates of chemical reactions; and special topics. Lectures, review sessions, and four hours of laboratory work per week. Students who have taken Chemistry 1102 may not take Chemistry 1109 for credit. To ensure proper placement, students must take the chemistry placement examination and must be recommended for placement in Chemistry 1109.

Teaching next semester

CHEM 2250. Organic Chemistry I, L3

Introduction to the chemistry of the compounds of carbon. Describes bonding, conformations, and stereochemistry of small organic molecules. Reactions of hydrocarbons, alkyl halides, and alcohols are discussed. Kinetic and thermodynamic data are used to formulate reaction mechanisms. Lectures, review sessions, and four hours of laboratory work per week.
