CHM2123/2523 (Fall 2018)

CHM2123/2523 Midterm and Final Exam Review Sessions.

The application of theoretical organic chemistry is fun for some and a bore to others. We will unravel the complexity of all the chemical reactions conducted in this course. Your instructor is a Ph.D. graduate from the University of Ottawa specializing in chemistry. With expert guidance you will be able to understand why you are doing an extraction or why you used that reagent on the counter. Stoichiometry will become second nature. Experimental conditions will be explained. You will relate the theoretical and practical concepts of organic chemistry. Everything you did in the lab will make sense through expert guidance and you will become an expert yourself!
