An advanced first course in which students attend three lectures, one recitation, and one four hour laboratory per week. Lecture classes, involving about 100 students, emphasize selected points from the weekly reading assignments and relevant applications of chemistry in related fields such as biology and materials science. Recitation classes, involving about 25 students, are used to discuss weekly assignments. Laboratory work includes both qualitative and quantitative analysis. This sequence will be taught for the first time this academic year, but in the next few years will replace Chemistry 11L-12L as the mainline sequence for first year students.
Students attend three lectures, one recitation, and one four hour laboratory per week.
Lecture classes involving 100-150 students are used to emphasize selected points from the weekly reading assignments. Recitation classes involving about 25 students are used to discuss homework assignments. Covers in one semester the major topics of Chemistry 11L and 12L and hence covers two years of high school chemistry in one semester. Laboratory work includes both qualitative and quantitative analysis. First year students who experience difficulty in Chemistry 23L may request placement in Chemistry 21L anytime during the first month of the course.
