Organic chemistry foundations

Because of its severe approximations, in using the Huckel method (1932) one ignores most of the real problems of molecular orbital theory. This is not because Huckel, a first-rate mathematician, did not see them clearly they were simply beyond the power of primitive mechanical calculators of his day. Huckel theory provided the foundation and stimulus for a generation s research, most notably in organic chemistry. Then, about 1960, digital computers became widely available to the scientific community. 

The goal of this text is to build on the foundation of introductory organic chemistry to provide students and other readers a deeper understanding of structure and mechanism and the relationships between them. We have provided specific data and examples with which to illustrate the general principles that are discussed. Our purpose is to solidify the student s understanding of the basic concepts, but also to illustrate the way specific structural changes influence mechanism and reactivity.

Understanding organic chemistry means knowing not just what happens but also why and how it happens. In this chapter, we ll look some of the basic ways chemists use to describe and account for chemical reactivity, thereby providing a foundation for understanding the specific reactions discussed in subsequent chapters.

In chapters 6 through 8,1 concentrate in considerable detail on two research schools that sought to unify organic chemistry and physical chemistry with theoretical foundations built on the ion and electron theory. These schools are loosely designated the "Paris" and the "London-Manchester" schools, where "school" connotes a network of personal and professional associations over several generations at the Ecole Normale Superieure, in the first case, and at London University and the University of Manchester, in the second case. 

It was only in 1959 that Guy Ourisson renovated the study of organic chemistry by organizing the Groupe d Etudes de Chimie Organique (GECO), to facilitate contact with chemists abroad and to rethink the theoretical foundations of modern organic chemistry. 89 That this was a project sorely needed is indicated by Micheline Charpentier-Morize s reflections on her doctoral thesis defense in 1958. Prevost presided over the jury. When she referred to the possible existence of a "p-complex" to explain reactivity, Prevost exclaimed, "Madame, if I have one reproach for you, it is that you know the modem theories too well. "90... 

However, by the 1920s, as we have seen, a self-conscious use of electron theory in a dynamical interpretation of the old static chemical molecule recovered dynamical theoretical foundations for organic chemists in what became the disciplinary specialization of physical organic chemistry. The theory of electron valency and organic reaction mechanisms, in particular, the theory of mesomerism, developed as a new theoretical chemistry, a little prior to wave mechanics, along a largely independent track.
