Depending on their prior preparation, students will choose one of three possible entries to studies in this Department. Students with an average or weak background in chemistry should enroll in Chemistry 5 and 7; students with a strong background in chemistry should enroll in Chemistry 10; students with outstanding chemical preparation may enroll at once in Chemistry 17 or 20. Most well prepared students who wish to pursue honors level concentration in chemistry or closely allied fields will elect the (10)+20+30+40+135 track. Others who start with 5+7+17+27 may join the other track by taking 135 and 40. Most students of life sciences, especially those preparing for medical school, will take 5+7 or 10 followed by 17 and 27. Students may not take both Chemistry 17 and 20 for credit. Since there is little or no overlap in content between Chemistry 27 and 30, students interested in a strong background in both bio-organic and theoretical organic chemistry may take both courses. The Science A Core requirement may be satisfied by taking any one of Chemistry 5, 7, 10, 17, or 20.

Certain courses in biochemistry and biophysics are listed under Molecular and Cellular Biology or Biophysics. See cross-listings at end of middle group course section. The Division of Engineering and Applied Sciences, the Department of Physics, and the Department of Earth and Planetary Sciences also list a number of courses of interest to chemists.

Primarily for Undergraduates

Because of the sequence of prerequisites for chemistry courses, the Department strongly recommends some work in mathematics as well as chemistry in the first year. Freshmen contemplating this program are urged to consult a member of the Chemistry Department in planning their work for the first year. Advice may be obtained in the Head Tutor’s Office, Science Center 114.
Chemistry 5. Introduction to Principles of Chemistry
Catalog Number: 7171
James E. Davis
Half course (fall term). M., W., F., at 9, one hour per week of discussion, and three hours per week of laboratory. EXAM GROUP: 2
Introduction to the structure and properties of atoms and molecules; chemical reactions and stoichiometry; properties of gases, liquids and solutions; phase transitions, chemical equilibrium; acid/base and solubility equilibria, energy relationships in chemistry; thermodynamics and electrochemistry.
Note: Chemistry 5–7 is the mainstream general chemistry sequence for students with typical high school chemistry backgrounds (one year) or for students with no previous study of chemistry. Calculus is not necessary for Chemistry 5, but a strong background in high school algebra is essential. Students who lack this algebra background should take Math Ar or Math Xa before attempting Chemistry 5. Students with very strong high school chemistry backgrounds may enroll instead in Chemistry 10, 17, or 20; see those course descriptions for details.

Chemistry 7. Principles of Chemistry
Catalog Number: 5118
Roy G. Gordon and Charles M. Lieber
Half course (spring term). M., W., F., at 9, and three hours a week of laboratory and discussion. EXAM GROUP: 2
Rates and mechanisms of chemical reactions; elements of nuclear physics and chemistry; quantum mechanics of light and particles, including the quantum structure of the periodic table, chemical bonding and photochemistry; coordination chemistry; structure and bonding in solids; selected topics from organic, inorganic and polymer chemistry with an emphasis on the relationship of structure properties.
Prerequisite: Chemistry 5 or equivalent, in particular: chemical equilibrium, the first and second law of thermodynamics, and elements of acid-base chemistry. A few simple operations of the calculus are developed and used. Fluency in precalculus secondary school mathematics is assumed. Exposure to secondary school physics will be helpful.

Chemistry 10. Accelerated Course: Foundations of Chemistry
Catalog Number: 1376
Dudley R. Herschbach and Eugene I. Shakhnovich
Half course (fall term). Lectures M., W., F., at 9, discussion section, and laboratory work averaging four hours a week, to be arranged. EXAM GROUP: 2
Physical principles in chemistry: atomic and molecular structure, thermodynamics, and chemical kinetics. Applications to reaction equilibria and mechanisms; electrochemistry; photochemistry; environmental chemistry, life sciences and materials chemistry; selected commonplace, exotic, and poetic phenomena. Laboratory work stresses the principles and techniques of quantitative chemistry.
Note: Open to students with strong secondary school courses in chemistry, physics and mathematics, and who are currently enrolled in Mathematics 1a (or equivalent preparation). To be admitted to Chemistry 10, students must obtain a satisfactory score on the Harvard Chemistry Placement Examination, given during freshman week, or must obtain permission of the instructor. Students who do not take this examination or do not achieve a satisfactory score should take Chemistry 5 and 7. Chemistry 10 may not be counted toward a degree in addition to Chemistry 5 or 7.

Chemistry 17. Principles of Organic Chemistry
Catalog Number: 5085

Half course (fall term). M., W., F., at 11, and a discussion section to be arranged. EXAM GROUP: 4
An introduction to structure, bonding, and reaction mechanisms of organic compounds; chemical transformation of the common functional groups; principles of organic synthesis.
Note: The Chemistry 17/27 sequence is intended primarily for students in the life sciences, whereas the 20/30 sequence is intended primarily for Chemistry concentrators and other students concentrating in the physical sciences. Either sequence satisfies the organic chemistry requirement for medical school. The content of Chemistry 17 is similar to that of Chemistry 20, so students may not count both courses toward the degree. On the other hand, Chemistry 27 and Chemistry 30 cover different material, so students may choose to take both courses for degree credit; students should ordinarily take the third half course only after completing either the 17/27 or 20/30 sequence.
Prerequisite: Open to freshmen with a score of 750 or higher in the College Boards or the Chemistry Placement Examination; to students who scored 4 or 5 on the Chemistry Advanced Placement Examination; and to students who achieved a grade of B or higher in either Chemistry 7, or 10. Others may enter only by permission of the instructor.

Chemistry 20. Organic Chemistry
Catalog Number: 0876
Gregory L. Verdine
Half course (spring term). Lectures, M., W., F., at 9, and a discussion section to be arranged. EXAM GROUP: 2
An introduction to structure, bonding, and mechanism of organic reactions; chemical transformation of the common functional groups in aliphatic and aromatic compounds; synthesis; determination of structure; infrared and NMR spectroscopy.
Note: The Chemistry 17/27 sequence is intended primarily for students in the life sciences, whereas the 20/30 sequence is intended primarily for Chemistry concentrators and other students concentrating in the physical sciences. Either sequence satisfies the organic chemistry requirement for medical school. The content of Chemistry 17 is similar to that of Chemistry 20, so students may not count both courses toward the degree. On the other hand, Chemistry 27 and Chemistry 30 cover different material, so students may choose to take both courses for degree credit; students should ordinarily take the third half course only after completing either the 17/27 or 20/30 sequence.
Prerequisite: Open to freshmen with a score higher than 750 in the College Boards or the Chemistry Placement Examination; to students who scored 5 on the Chemistry Advanced Placement Examination; and to students who achieved a grade of B or higher in either Chemistry 7, 9, or 10. Others may enter only by permission of the instructor.
