Electronic Charges of Bonds in Organic Compounds discusses trends in the electronic theory of structure and reactivity of organic compounds. This book focuses on simple and diverse methods that calculate the electronic charges of bonds from the results of physical methods of investigation.
This text is divided into 10 chapters. In Chapter I, brief information is provided about the work of other research workers on the electronic charges of bonds and organic compounds. Chapters II to VI elaborate on the relationship of the electronic charges of bonds to the physical and physicochemical characteristics of molecules and their structural elements. The relationship between the electronic charges of bonds and chemical properties are explained in Chapters VII to X.
This publication provides a good reference for students and researchers conducting work on electronic charges of bonds and reactivity of organic compounds.
