Chemistry (CHEM)

Chair: A. Chianese
DEPARTMENT SITE

A major in chemistry or biochemistry is suitable for students who wish to prepare for careers in the chemical profession or in the related fields of life, health, or earth sciences. Many graduates go on to post-graduate programs in biochemistry, chemistry, chemical physics, pharmacology, medicine, dentistry, or veterinary medicine. Recent chemistry and biochemistry students have also pursued careers in law, business, teaching, and other fields.

The two courses listed are available for first-year students; the course you select depends on your background in high school science and mathematics. The standard course is CHEM 101/101L, the first half of a two-semester General Chemistry sequence. An accelerated introductory course (CHEM 111/111L) is available for students who had extensive high school chemistry preparation (see below).

Introductory chemistry (CHEM 101/101L and 102/102L, or CHEM 111/111L) is crucial for students interested in the health sciences (medical, dental, veterinary schools) because it is not only required for admission to those graduate programs, but is also a prerequisite for both Organic Chemistry (CHEM 263/263L and 264/264L) and Molecules, Cells, and Genes (BIOL 182/182L). Students interested in biology, molecular biology, biochemistry, or chemistry should enroll in the appropriate introductory chemistry course during the fall semester of their first year at Colgate. Please note that neither CHEM 101/101L nor CHEM 111/111L are offered in the spring term.

CHEM 101 (fall term only) meets three times a week for lectures and also includes a required three-hour laboratory session (CHEM 101L) each week. A year of high-school chemistry (or its equivalent) is recommended for students taking CHEM 101/101L. A section of CHEM 101 is also available for students who have had little or no prior chemistry instruction. This section (CHEM 101 S) includes two supplemental meetings per week for problem solving and peer tutoring in addition to the regular three classes and one laboratory section (CHEM 101L) per week. Admission to CHEM 101 S is granted by permission or invitation only, and may also be added during the drop/add period. Students who wish to be considered for this section should request CHEM 101 S as one of their preferred courses.

CHEM 111 is a one-semester general chemistry course (fall term only) for the well-prepared first-year student. CHEM 111 meets three times a week for lectures and also includes a three-hour laboratory session (CHEM 111L) each week. Admission to CHEM 111/111L is limited to students who meet one of the following criteria: AP Chemistry scores of 4 or 5, IB higher level Chemistry scores of 6 or 7, international A-level scores of B or A, or a 650 or higher on the SAT II Chemistry Exam.

Completion of either CHEM 111 or CHEM 101/102, and their required labs, fulfills the prerequisite requirements for further study in chemistry, including Organic Chemistry (CHEM 263).

Advanced Placement

Colgate course credit is awarded to students receiving a score of 4 or 5 on the AP Chemistry exam. Students receiving a score of 5 will be awarded credit for CHEM 101 and 102. Students receiving a score of 4 will be awarded credit for CHEM 101 and then may enroll in CHEM 102/102L in the spring term, or take CHEM 111/111L in the fall term. While a score of 5 on the AP exam can qualify a student for direct entrance into CHEM 263/263L, experience has shown that students with scores of 4 or 5 are best served by taking one AP credit (CHEM 101) and enrolling in CHEM 111/111L in the fall term of their first year. Students with AP scores of 3 or less should enroll in CHEM 101/101L. If you have questions about how to best use your AP course credits, please see the department chair (or any member of the department) during Orientation.

Students who wish to keep open the option of majoring in chemistry or biochemistry are strongly urged to take CHEM 101/101L or 111/111L and the appropriate mathematics course (MATH 111 or 112) during their first semester at Colgate. 

Courses

View all with day/time information
CHEM 101, General Chemistry I
The first half of a two-term sequence that introduces chemical principles that apply to all areas of chemistry. This course deals with molecular and reaction stoichiometry, gases, the first law of thermodynamics, the electronic structure of atoms, the periodic table, chemical bonding, and molecular geometry.

CHEM 101L, General Chemistry I Lab
Required corequisite to CHEM 101.

CHEM 111, Chemical Principles
A one-term course designed for the well-prepared first-year student. CHEM 111 covers many of the same fundamentals covered in CHEM 101 and 102, but treats those ideas in greater depth. Enrollment requires a score of 4 or 5 on the AP exam, an A or B on A-level exam in chemistry, a score of 6 or 7 on the higher level IB chemistry exam, or a 650 or higher on the SAT II Chemistry Exam. Students enrolled in CHEM 111 who meet the standards by the AP exam may receive only one advanced placement credit for general chemistry. CHEM 111 (or CHEM 101-102) serves as a prerequisite for CHEM 263, 264 (Organic Chemistry), or CHEM 333, 334 (Physical Chemistry).

CHEM 111L, Chemical Principles Lab
Required corequisite to CHEM 111.
