Synthesis of new compounds and proving their structure is one of the main tasks of organic chemist and its design requires a sound knowledge of the functional groups of organic compounds (Nomenclature, physical and chemical properties), stereochemistry and investigation of organic reaction mechanisms. Doing organic synthesis is the real test of your ability to use the reactions of organic chemistry. This book is primarily designed to offer basic understanding of structures, reactivates and synthesis of simple organic compounds and the relationships between structure and properties. The four major classes of Organic Reactions: Substitution, Elimination, Addition and Rearrangement reactions and their reaction mechanism as well as the factors affecting them (resonance effect, steric effect, inductive effect, solvent effect, the substrate and the like) are also discussed. Moreover, the application of all classes of Organic Reactions in synthesizing of new organic compounds is presented with ample examples. This book is a valuable material for advanced students and industrial researchers in organic, medicinal, pharmaceutical, dye, leather, paper, polymer and agricultural chemistry.
