Chemistry courses deal with the nature and composition of matter and the laws that govern chemical reactions. These courses are offered to meet the needs of three groups of students: those who choose to make chemistry or chemical engineering their profession; those who require a certain amount of chemistry as an adjunct to some related vocation; and those who desire a knowledge of chemistry as part of a general education.
Students expecting to major in any of the basic sciences should take either (1) Chemistry 125, 126 and the associated laboratories, Chemistry 135, 136 or (2) the more accelerated Chemistry 140. These courses offer an introductory survey of all fields of chemistry (inorganic, analytical, organic, physical, and biochemistry). An extended study of chemistry for the nonmajor may be obtained by taking Chemistry 245, 246, 345, 388, or BBMB 325. Premedical students should note that most medical schools require for entrance a full year of organic chemistry lecture and two credits of organic laboratory.
There are two ways to fulfill first-year general chemistry requirements. One is by taking the yearlong General Chemistry series of courses (Chemistry 125, 126, 135, 136). An accelerated option is to take a semester of Advanced General Chemistry (140 and 140 lab). Students with an AP score of 4 or 5 do not have to take 125 but should take 135 in the fall. Students with an AP score of 5 may take 140 and 140 lab and receive almost a full year of general chemistry credit (three credits for their AP score, three credits for the 140 lecture, and one credit for the 140 lab). Note: AP credit does not include credit for the Chemistry 135 lab.
The department also offers two one-semester courses in chemistry (Chemistry 100 and 102) for the student wishing a general knowledge of the field to fulfill breadth of study requirements.
The department is well-equipped with instrumentation for chemical analysis. A “hands on” policy allows extensive use of the instruments, beginning in the first year with experiments involving pH meters, analytical balances, and visible spectrophotometers. In advanced courses, students are introduced to atomic absorption, infrared and fluorescence spectroscopies, nuclear magnetic resonance spectrometry, ultraviolet spectrophotometry, mass spectrometry, capillary electrophoresis, gas chromatography, high-performance liquid chromatography, and electrochemistry. The aim is to give practical experience with modern chemical instrumentation so that students can learn not only what an instrument does but also how it works. In advanced courses, students will use various computer software packages for data analysis and presentation, and for laboratory report writing.
A student who enters Whitman without any previous college-level chemistry courses will need to complete 36 chemistry credits to fulfill the requirements for the major. Additional credits are required in other departments. These are listed below with the requirements for the chemistry major. Courses completed in the chemistry department apply to the science and quantitative analysis (selected courses) distribution areas.
The Chemistry major: A minimum of 36 credits in chemistry, including:
Either Chemistry 125, 126, 135, 136, or Chemistry 140; and Chemistry 240, 245, 246, 251, 252, 320, 345, 346, 360, 370, and at least three credits of Chemistry 490 or 498. A minimum grade of C (2.0) is required in either Chemistry 240 or Chemistry 345, whichever is taken first. Students contemplating a major in chemistry are encouraged to take Chemistry 240 in their sophomore year.
The following nonchemistry courses also are required: Mathematics 125, 126, and 225; and either Physics 155 and 156 or Physics 165 and 166, or one year of college-level physics for science majors with lab taken elsewhere. Students who wish to complete the American Chemical Society certified chemistry major also must complete BBMB 325 (note that Biology 111 is a prerequisite). Students who plan to pursue graduate work in chemistry are recommended to obtain additional coursework in mathematics, which may include Mathematics 244, 300 or 367, or possibly in biology, and should consult with their adviser.
Subsequent to the declaration of a chemistry major or minor, no chemistry courses within the major or minor may be taken on a P-D-F basis.
Senior Assessment in Major: The successful completion of a chemistry degree requires the student to pass both a comprehensive written examination and a one-hour oral examination.
The Chemistry minor: A minimum of 19 credits in chemistry, involving either of the following sequences: (1) 125, 126, 135, 136, 245, 246, 251, 252; at least one of the following: 240, 345, 388, BBMB 325; or (2) 140, 245, 246, 251, 252; at least two of the following: 240, 345, 346, 388, BBMB 325. Any 300-400 chemistry course may be substituted for 300-level credit.
The Biochemistry, Biophysics, and Molecular Biology (BBMB) major: See BBMB under the Courses and Programs section in the catalog for a description of the courses and major offered at the interface of biology, chemistry, and physics.
The Chemistry-Geology combined major: Either Chemistry 125, 126, 135, 136 (or 140), 240, 346, 320 (or 388); either Geology 110, 120, or 210 and 227, 343, 346, 350, 460, 470, a minimum of one credit in 358; Mathematics 125, 126, Physics 155. Chemistry 320 or 420 is recommended. Courses completed in this major apply to the science and quantitative analysis (selected courses) distribution areas. Seniors completing the chemistry-geology major will complete a written exam constructed by the geology faculty, a written exam constructed by the chemistry faculty, and an oral exam conducted jointly by faculty in both departments. Additionally, all students are strongly encouraged to complete a senior research project under the guidance of a faculty member in either of the two disciplines, registering for a minimum of three credits in either Chemistry 490 or 498 or Geology 490 or 498.

460 Bioinorganic Chemistry
3; not offered 2013-14
This course will examine the role of trace metal ions in biological systems. Metal ions such as iron, copper, and zinc are essential for life and are required for the function of about one-third of all known enzymes. However, the inherent toxicity of these metals has led to the evolution of cellular machinery to control the uptake, transport, storage, and distribution of trace metals in organisms. This toxicity also has been exploited in the development of several metal-based drugs. The challenges of understanding the roles of trace metals in biological systems have led to the development of novel techniques for their study. The course will survey a selection of these methods, and will examine case studies of metal-containing enzymes, metal ion trafficking, and metal-based drugs. A major portion of this course will be student-led literature reviews, presentations, and discussion of these topics. Prerequisite: Chemistry 360 or BBMB 325 or consent of instructor.
