From the calendar

Official source · Faculty of Arts & Science

An introductory course in organic chemistry, based around the themes of structure, bonding, reaction mechanism, and synthesis. Reactions are discussed with a view to understanding mechanisms and how they are useful in the multi-step synthesis of medicinally and industrially important compounds. An introduction to the spectroscopy of organic molecules is also given, as well as a discussion of topics relating to the biological behaviour of organic molecules and medicinal chemistry. Students are also introduced to green chemistry approaches from an experimental perspective. This course continues from CHM151Y1 or CHM136H1 and is designed for students enrolled in any chemistry specialist or major program. (Lab Materials Fee: approximately $40).

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.

This rests on 2 reported terms. It is shown because hiding it would not make it less true, but one or two results are a datapoint, not a distribution — a single unusual cohort moves this number a long way.

Counts, not a library. Pyko does not host or distribute course files, and this page is not an offer to supply one — the archive is what lets these pages describe how a course is assessed, which matters most where no syllabus has been verified.

Assessment weightingNo syllabus we can lawfully use has been verified for this offering. Contribute yours and the breakdown appears here.
Per-term breakdownHeld back deliberately. Splitting 2 observations across terms would be false precision.
Instructor-level detailAverages are not split by instructor. At these sample sizes the difference between sections is noise, not signal.

What this opens up

20 courses list CHM249H1 as a prerequisite

The other 13 have no page yet. Listing a course here means it names CHM249H1 among its prerequisites — often as one of several ways to satisfy the same requirement, so this is what CHM249H1 makes available, not what it alone guarantees.
