Official source · Faculty of Arts & ScienceCHM135H1 and CHM136H1 cannot be taken in the same session. This course offers an introduction to organic chemistry with an emphasis on the fundamental principles of structure, bonding, reactivity, and structural identification of organic molecules. Chemical reactivity is discussed from a mechanistic perspective and includes an introduction into multi-step synthesis of organic compounds, with a focus on the reactivity of pi-bonds as electrophiles (aldehydes, ketones, carboxylic acids) and as nucleophiles (alkenes). Students are also introduced to green chemistry principles, primarily in the laboratory, where practical skills are introduced to understand, identify, separate, and prepare organic compounds with a focus on biological or medicinally relevant examples. This course is recommended for students in life and health science programs. (Lab Materials Fee: approximately $27).

What people actually got

This is a student-contributed aggregate, not an official University of Toronto record. It is also not a measure of how hard the course is — a course average moves with who enrols in it, not only with the material.
Per-term figures stay hidden until each term clears five contributors. 9 observations can support one honest number; they cannot support 9.

What this opens up
26 courses list CHM136H1 as a prerequisiteThe other 10 have no page yet. Listing a course here means it names CHM136H1 among its prerequisites — often as one of several ways to satisfy the same requirement, so this is what CHM136H1 makes available, not what it alone guarantees.
