Book excerpt: Excerpt from The Chemistry of the Non-Benzenoid Hydrocarbons and Their Simple Derivatives The beautiful, interesting, and often facile chemistry of the benzene hydrocarbons has somewhat overshadowed the chemistry of the aliphatic open chain and cyclic non-benzenoid hydrocarbons. Certainly the chemistry of the former series has been much more fully rounded out. Judging from the customary method of treatment accorded them in our textbooks, there is some confusion in the arrangement of subject matter which does not give the student a proper idea of the close relationships and similarity of chemical behavior possessed by all the non-benzenoid hydrocarbons. Mr. Wells, in his "Outline of History," says: "There is a natural tendency in the human mind to exaggerate the differences and resemblances upon which classification is based, to suppose that things called by different names are altogether different, and that things called by the same name are practically identical. This tendency to exaggerate classification produces a thousand evils, . .." This tendency, which Mr. Wells deplores, is well shown by the use of the term "hydro-aromatic" hydrocarbons and the classification of cyclohexane and its derivatives with benzene. This term is still employed for cyclohexane and its simple derivatives, although its behavior is almost identical with that of normal hexane. The same applies to cyclopentane and its simple derivatives as compared with normal pentane, yet cyclopentane cannot be termed a "hydro-aromatic" hydrocarbon. Cycloheptane, cyclooctane, cyclononane, cyclobutane and cyclopropane should certainly be classed and described together with cyclohexane, as indeed Aschan and a few others have done. The differences in chemical properties between benzenoid ring systems and Non-Benzenoid hydrocarbons are well established, but in spite of the enormous amount of work done, have not yet received adequate explanation. As regards the aliphatic hydrocarbons proper, these fare very badly in most works on organic chemistry, particularly in the briefer textbooks. Usually, the entirely erroneous statement, or implication, is made that the so-called type reactions given for the first two or three members of the methane series hold good for the higher members.
