3.00 Credits
This course offers a rigorous, foundational treatment of atoms and molecules. We study the nature of chemical bonding and how bonding gives rise to the three-dimensional structure of matter. We explore how the macroscopic properties of substances can be interpreted in terms of atomic and molecular structure. We also learn mathematical and conceptual tools for quantifying chemical equilibrium, with an emphasis on the reactions of acids and bases. Laboratory work reinforces concepts in lecture, and also provides a review of fundamental topics, such as stoichiometry, gas laws, and solution-phase reactions, that are essential for future course work in chemistry. Prerequisites: none. Three lectures and one three-hour laboratory per week. Lab/materials fee is required. Fall semester. (4 credits)

3.00 Credits
This course provides an intuitive, yet rigorous, understanding of how energy is stored and transferred in chemical systems. We start with the behavior of individual atoms and molecules (using the foundation of atomic and molecular structure laid in Chemistry 111), and then build up to the macroscopic concepts of thermodynamics. We focus on free energy as a powerful tool for predicting physical and chemical behavior. We then apply our understanding of energetics to electrochemical systems and the rates of chemical reactions. Prerequisite: Chemistry 111 or satisfactory performance on a placement examination. Three lectures and one three-hour laboratory per week. Lab/materials fee is required. Spring semester. (4 credits)

3.00 Credits
This course combines topics from both Chemistry 111 and 112 and is meant to be an accelerated one-semester version of General Chemistry. The course begins with a rigorous treatment of atomic and molecular structure, and explores various modern models of chemical bonding. These ideas are applied to a thorough discussion of chemical thermodynamics and kinetics. Conceptual and mathematical methods for quantifying chemical equilibrium are also explored, with particular emphasis on the chemistry of acids and bases. Prerequisites: AP chemistry score of 4 or 5; IB chemistry score of 5, 6, or 7; or satisfactory performance on a placement examination (administered during Orientation Week). Some knowledge of calculus is recommended. Three lectures and one three-hour laboratory per week. Lab/materials fee is required. Fall semester. (4 credits)

3.00 Credits
This course develops a broad understanding of the theoretical concepts of organic chemistry. Molecular orbital theory and valence bond resonance theory are invoked to describe and explain the ramification of covalent bonding in organic molecules, as well as to rationalize fundamental noncovalent associations. Thermodynamic considerations of 3-dimensional molecular shape are discussed. Contemporary instrumental techniques for the assignment of molecular structure are a key focus. Modern mechanistic theory of organic chemical reactions is developed in the context of acid-base, nucleophilic substitution, elimination, and electrophilic addition reactions. Prerequisite: Chemistry 112 or 115. Three lectures, four hours laboratory per week. Fall semester. (4 credits)
-
3.00 Credits
This course further develops the theoretical concepts of organic chemistry, and helps students to develop an ability to propose plausible synthetic pathways to organic molecules. Particular focus is on nucleophilic addition, electrophilic substitution, free radical, and pericyclic reactions. Prerequisite: Chemistry 211. Three lectures, four hours laboratory per week. Spring semester. (4 credits)
-
3.00 Credits
This course uses key concepts of chemical equilibrium and structure to solve problems in chemical analysis. Lecture and laboratory work provide both the theoretical foundations and practical training in classical methods (gravimetric and volumetric analysis), atomic and molecular spectroscopy, and chromatography. Statistics and error analysis are also emphasized throughout the course. Prerequisite: Chemistry 112 or 115. Three lectures, four hours laboratory per week. Spring semester. (4 credits)
-
3.00 Credits
This course develops understanding of computation, advanced NMR and mass spectrometric techniques as applied to research efforts in organic chemistry and related fields, such as pharmaceuticals, materials science, supramolecular synthesis, and crystal engineering. Prerequisites: Chemistry 212 and permission of the instructor. Three lectures per week. Spring semester. (4 credits)
-
3.00 Credits
Presentations on current topics in the molecular sciences by campus visitors, as well as by Macalester students and faculty. Students may be expected to prepare for the presentations by reading, and, in some cases, discussing the work of a speaker in advance of his/her seminar presentation. Chemistry majors will make two oral presentations over four semesters. All students will submit a written synopsis for three seminar presentations each semester. Prerequisite: junior or senior standing. One hour per week. Every semester. (1 credit)
-
3.00 Credits

Prerequisites: Chemistry 112 or 115, Physics 227, Mathematics 137. Three lectures and three hours laboratory per week. Fall semester. (4 credits)
-
3.00 Credits
Topics in microscopic, modern physical chemistry: quantum mechanics and atomic and molecular structure; computational chemistry; symmetry and group theory; spectroscopy and diffractometry; and statistical mechanics. Prerequisites: Chemistry 112 or 115, Physics 227, Mathematics 137. Recommended: Mathematics 237. Three lectures and three hours laboratory per week. Spring semester. (4 credits)
