FORMULA INDEX. THE following index of organic coinpounds of known empirical formula is arranged according to Richter’s system (see Lexikon der Kohlenstof- Verbindungen). The elements are given in the order C H 0 N C1 Br I F S P and the remainder alphabetically. The compounds are arranged-Firstly in groups according to the number of carbon atoms (thus C1 group, C group etc.). Secondly according to the number of other elements besides carbon contained in the molecule (thus 5 IV indicates that the molecule contains five carbon atoms and four other elements). Thirdly according to the nature of the elements present in the niolecule (given in the above order). Fourthly according to the number of atoms of each single element (except carbon) present in the molecule. Salts are placed with the compounds from which they are derived.The chlorides, bromides iodides and cyanides of quaternary ammonium bases however are registered as group-substances. C1 Group.
