Chemistry is often called the central science, overlapping significantly with biology, physics, psychology, mathematics, geology and engineering. All studies of matter at the molecular level (for example, biochemistry, molecular biology, pharmacology, neuroscience, nanoscience, computational chemistry, solid-state physics, geochemistry, the environmental sciences, and material science and engineering) depend on the theories and methods of chemistry.
The first semester of introductory chemistry is offered at two levels. CHEM 121 is a lecture-and-discussion course intended to give students a thorough introduction to the fundamental concepts, theories and methods of chemistry; enrollment priority is given to first- and second-year students. CHEM 122 is an accelerated lecture course covering a full year of general chemistry in one semester and is designed for students with previous study of chemistry. These two courses meet at the same time. CHEM 123 is the accompanying lab course, highly recommended for students in CHEM 121 and required for students in CHEM 122.
Students who have successfully completed CHEM 121 can then choose a second-semester lecture-and-discussion course based on their particular interests. CHEM 124 continues the investigation of chemical principles as they apply to issues in modern chemistry, such as sustainability, neurochemistry, biochemistry and molecular medicine. CHEM 126 is the accompanying lab course, highly recommended for students in CHEM 124. Students who complete CHEM 122 may enroll directly into CHEM 243 in the spring and get an early start on the upper-level curriculum.
Completion of one of the introductory lecture and lab sequences (either CHEM 121, 123, 124 and 126 or CHEM 122 and 123) is a prerequisite for enrolling in organic chemistry or any other advanced chemistry courses. Transfer students or those with exceptionally strong secondary-school preparation in chemistry may be invited by the department, after completing an interview with the organic faculty, to begin their studies in organic chemistry.
Students planning to complete medical school requirements should, in their first year, plan to take either the traditional introductory chemistry sequence (CHEM 121, 123, 124 and 126) or the accelerated sequence (CHEM 122, 123, 231 and 233). Please consult with your likely applicant medical schools regarding exact chemistry requirements for each school. The following combinations should satisfy the medical-school requirements for courses in general chemistry: CHEM 121, 123, 124 and 126; CHEM 122, 123, 124 and 126; or CHEM 122, 123 and 243. The organic requirements should be satisfied by CHEM 231, 232, 233 and 234.
The department also offers several courses designed for students who are not planning to continue beyond one or two semesters of study. These "non-majors" courses, which are numbered below 120 and have no prerequisite, serve various purposes. CHEM 109 is a required core course for the concentration in neuroscience, and CHEM 108 or CHEM 110 is a required core course for the concentration in environmental studies. Students wanting to complete the College requirements for 1 unit in the natural sciences can take any two of these, and CHEM 108 satisfies the College quantitative reasoning (QR) requirement. Non-majors courses do not serve as a prerequisite for any higher-numbered courses in the department.
The chemistry curriculum begins with a series of courses covering introductory chemistry and organic chemistry in the first two years, then branches out to advanced topics in physical, inorganic and analytical chemistry and biochemistry. Because of this vertical structure, we advise students to begin their study of chemistry as soon as possible in order to build upon their secondary-school preparation in math and science, the roots of college chemistry.
Students who are considering a chemistry, biochemistry or molecular biology major should plan to take CHEM 121 and 123 or CHEM 122 and 123 in their first semester and continue on with the appropriate chemistry courses in the second semester, either CHEM 124 and 126 or CHEM 231 and 233. The chemistry major is rounded out with an offering of courses and labs on the major subdisciplines of the field, along with seminar-style special topics courses. Opportunities to work on independent research projects are available at all levels of the curriculum.
A capstone Chemistry Research Seminar for seniors in the fall semester guides students through a self-study of an individual research topic, and the Senior Exercise in the spring semester involves preparing and presenting a 30-minute talk on two research papers on the senior research topic.
Chemistry majors are well prepared for professional employment or graduate study in chemistry, biochemistry and related fields; the health sciences such as medicine, dentistry and nursing; the veterinary sciences; secondary-school teaching; engineering; the environmental sciences; business and law; and public service. The major emphasizes the development of independent, critical thinking as well as problem-solving and communication skills. Our department is accredited by the American Chemical Society (ACS), and students may elect to receive a degree certified by the ACS (see below).
Numerous opportunities exist for students to participate in the life of the department through (1) undertaking research with faculty members, (2) participating in social and outreach activities, (3) advising the department in the hiring and evaluation of faculty members and other matters, and (4) working as stockroom assistants, laboratory proctors, paper graders and tutors.
The minimum requirement for a chemistry major is 6 units of credit in the department, including the following:
CHEM 123 and CHEM 126
CHEM 121 and CHEM 124
CHEM 123 and CHEM 126
CHEM 231 with CHEM 233
CHEM 370, 371, 372, 374
.5 unit of CHEM 375 may replace one advanced lab (.25 unit)
In addition, a year of introductory physics lecture (PHYS 130, 135 or 140, 145) with lab (PHYS 141, 146), and Calculus B (MATH 112) are highly recommended. Students planning to do graduate work in chemistry or related areas should take additional advanced courses in chemistry and the natural sciences division and partake in research opportunities during the school year and summer. For a degree to be certified by the American Chemical Society, a student must complete 1.5 units of introductory physics, the minimum chemistry major plus CHEM 256 and 1 unit of research in CHEM 375.
The chemistry and biology departments offer interdisciplinary majors in biochemistry and molecular biology. Refer to the biochemistry and molecular biology section in this catalog for descriptions and course requirements. We encourage students to take upper-level courses in departments affiliated with chemistry (biology, physics, mathematics, neuroscience or psychology). With department approval, one of the required advanced labs can be replaced with 1 unit of selected 200- or 300-level coursework in another department.
The Senior Exercise in chemistry has two components, one written and one oral. At the end of the fall semester, students submit a review paper on an assigned topic. During the spring semester, senior chemistry majors must prepare and present a 30-minute talk on two research papers relating to their senior research topic. See the chair and the department website for more information.
Departmental honors in chemistry involve demonstrating excellence in both depth and breadth of the discipline, through accomplishments on a specific research project and achievement in studying the principal areas of chemistry knowledge. Students wishing to pursue senior honors research in chemistry should apply to the chemistry department chair no later than April 15 of their junior year. See the chair and department website for more information.
The minor in chemistry requires a minimum of 2.5 units of credit earned in the chemistry curriculum; these include completion of introductory chemistry (CHEM 122 or CHEM 124), the introductory laboratories (CHEM 123 and CHEM 126), an advanced seminar (CHEM 401), and two upper-level lectures from CHEM 231, 232, 243, 256, 335, 336 or 341, or additional sections of 401.
