The Nature of the Chemical Bond provides a general treatment, essentially nonmathematical, of present (as of 1960) knowledge about the structure of molecules and crystals and the nature of the chemical bond. Among the new features in the third edition are a detailed resonating-valence-bond theory of electron-deficient substances, such as the boranes and ferrocene; a chemical theory of the electronic structure of metals and intermetallic compounds; a discussion of the role of the hydrogen bond in the structures of proteins and nucleic acids; the electroneutrality principle; and other new principles of molecular structure.
A far cry from modern books on molecular quantum mechanics which (rightly) use actual physical tools to interpret bonding, this book's conceptual arguments and prose explanations nevertheless had a big influence on me when I cracked it open in grad school.
I don’t think I had enough foundational knowledge about chemistry for this book. It has a lot of very high level chemistry concepts without any real build up to them. The book is very good at describing chemical structures and lists a lot of experimental data. It seems to be a good reference book and I read the abridged version of the book so that may explain why I felt it was lacking some in its explanations. I think to enjoy this book you really have to be in the thick of chemistry and know a lot about chemistry already. Once I read more foundational chemistry books I may give it a reread.
