Organic Chemistry III: Heterocyclic Chemistry (Theory)
|
CO95: Describe some of the important methods of preparation and properties of aliphatic and aromatic nitro and amino compounds mechanistically. Discuss the mechanism of diazotization and their applications. CO96: Discuss the preparation and properties of some prescribed poly-nuclear hydrocarbons and their important derivatives. CO97:Outline mechanisms for reactions involving heterocycles (five and six membered) as starting materials and propose syntheses of heterocycles from the major classes. CO98: Explain the structure, preparation and properties of some fused ring heterocycles. CO99: Classify different types of alkaloids, and terpenoids and discuss their chemistry & medicinal importance. CO100: Contribute effectively in course-specific interaction. |
Approach in teaching: Interactive lectures, tutorials, group discussions and e-learning.
