CHM course changes (starting Fall 2025)

Change 1: Four introductory CHM courses will be split into individual lecture and lab components

Starting in Fall 2025, several CHM classes will be changed so that their lecture and labs will be separated into different courses. Their course numbers will be changed, and lectures and labs will no longer be linked at registration:

CHM 115 (Principles of Chemistry I) will be split into

  • CHM 125 (lecture) and CHM 126 (lab)

CHM 116 (Principles of Chemistry II) will be split into

  • CHM 127 (lecture) and CHM 128 (lab)

CHM 241 (Organic Chemistry for Life Sciences I) will be split into

  • CHM 235 (lecture) and CHM 236 (lab)

CHM 242 (Organic Chemistry for Life Sciences II) will be split into

  • CHM 237 (lecture) and CHM 238 (lab)

Starting in Fall 2025, all programs/majors that currently require CHM 115 will now require CHM 125/CHM 126 (and likewise for the other classes). Students should simply substitute the lecture/lab courses for the older combined class. The lecture and lab are corequisites--they must be taken together the first time. However, students may repeat an individual lecture or lab component without repeating the other component.

Change 2: CHM 230 and CHM 232 are sunsetting and will be replaced by CHM 234

CHM 230 (Introduction to Organic and Biochemistry) and CHM 232 (Biological Chemistry) will be taught for the last time in Summer 2025. Starting in Fall 2025, we will be teaching CHM 234 (Introductory Biochemistry). Students in majors or programs that previously required CHM 230 or CHM 232 in the past should now register for CHM 234.

  • Some programs previously required CHM 109 and CHM 230--those students students should now take CHM 109 and CHM 234.
  • Some programs previously required CHM 109, CHM 231 and CHM 232--those students should now take CHM 109, CHM 231 and CHM 234.

Change 3: New numbers for two CHM electives

A few years ago our advanced organic lab and lecture courses (CHM 441 and CHM 447) were combined into a single course with the temporary designation CHM 480, and offered in the Fall. Similarly, our advanced inorganic lab and lecture courses (CHM 471 and CHM 477) were combined into single course with the temporary designation CHM 480, and offered in the Winter. We have now established official numbers for these courses:

  • CHM 480 (Advanced Organic Chemistry) will be CHM 448 (Every Fall)
  • CHM 480 (Advanced Inorganic Chemistry) will be CHM 478 (Every winter)
