Aromatici y I. Introduction 0 0 0 The classification of organic compounds is based on the structure of the molecules. compounds have open-chain structures such as bonds. In molecules, the carbon atoms form a cyclic structure , as in cyclohexane (2 ) and cyclohexene (3). compounds are unsaturated cyclic molecules that possess additional stability as a result of the arrangement of .Tc-electrons associated with the unsaturation of the ring system. This book will concentrate on the chemistry of benzene (4) and its derivatives and relat ed polynucle ar hydrocarbons. Aromatic compounds are also known as ; they can be , indicating that the ring skeleton con- tains only carbon atoms, or , with at least one atom other than carbon in the ring. These heteroatoms are typically N, 0 or S . Heterocyclic compounds, which can be aromatic or alicyclic, are covered in another book in this series. Initially, we will look at wha t distinguishes aromat ic compounds from other cyclic molecules and how chemists’ understanding of aromaticity has developed up to the present day. hexane (1 ) and can contain singl e (C-C), double (C=C) and triple (C=C) 1 2 3 4
