'Pharmaceutical Organic Chemistry III - Theory' is a course offered in the fourth semester of B. Pharm program at School of Pharmacy, Health Sciences campus, Amrita Vishwa Vidyapeetham.

Course Duration: 45 Hours


This subject imparts knowledge on stereo-chemical aspects of organic compounds and organic re- actions, important named reactions, chemistry of important hetero cyclic compounds. It also emphasizes on medicinal and other uses of organic compounds.


At the end of the course, the student shall be able to

  1. Understand the methods of preparation and properties of organic compounds
  2. Explain the stereo chemical aspects of organic compounds and stereo chemical reactions
  3. Know the medicinal uses and other applications of organic compounds

Note: To emphasize on definition, types, mechanisms, examples, uses/applications
