CHEM321 Organic Chemistry II

Chem: 321 Organic chemistry II Theme Functional group transformations. 

Objectives: To analyse the structure of given organic molecules and identify reaction centers. Recognize the reactivity pattern. Predict the outcome of the reaction. Explain the mechanism

Organic chemistry concepts related to functional group transformations will be discussed. A mechanism based approach will be adopted. Factors contributing to the reactivity pattern will be discussed. Discussion will be centered around analysis of structure of given organic substrate, identification of reactive parts of the molecule, recognizing the electronic nature of the reaction centers and reagents, predicting overall transformation and justifying the transformation.
