Originally published in 1969, this book analyses the special properties of benzene and its derivatives, which give them their distinct aromatic character. The text first discusses the structure of benzene, including the light shed on it by physical methods and wave mechanics, and the structure of polycyclic benzenoid hydrocarbons and heterocyclic aromatic compounds. Aromaticity is defined as a function of the electronic structure of the molecule or ion in question and it is shown that this has important consequences in respect of bond lengths, resonance energies, electronic absorption spectra and induced ring currents. Final chapters discuss how far aromatic character and aromaticity are associated with non-benzenoid hydrocarbons and with more complex systems.

This 1954 book was the first to be devoted to the fundamental properties of the aromatic compounds as a whole. It describes the experimental and theoretical attempts to explain their structure and discusses their characteristic properties and the mechanism of their reactions. Heterocyclic compounds are included in Dr Badger's survey. Aromatic compounds are characterised by their cyclic molecular structure, their high degree of unsaturation and their stability. Coal tar is the chief source of aromatic compounds, but they are also made from crude oil and can be produced synthetically. Nearly all dyestuffs are 'aromatic', as are most of the common drugs and explosives. The book addressed itself primarily to graduates and final-year undergraduates. It was also of interest to research chemists in the dyestuffs, pharmaceutical and explosives industries. As some complex aromatic compounds produce cancer on the skin of laboratory animals, cancer research workers will also have found it relevant.
