Learning outcomes expected at the level of the course (4 to 10 learning outcomes) |
After completing the course, the student will become familiarized with the major concepts of organic chemistry, which includes:
- identifying and naming of organic compounds according to functional groups and compare their physico - chemical properties;
- learn about the organic compounds isomerism, stereochemical designations, features, and separation;
- learn about organic compounds structure determination by spectroscopy (MS, NMR, IR, and UV/Vis);
- analyze the reactivity of organic compounds with respect to their structure and stereochemistry;
- propose appropriate reaction mechanisms of organic molecules that include addition, substitution and elimination;
- identify and interpret division, structure and properties of natural organic compounds ( carbohydrates, nucleic acids and lipids ). |
