The Subject Index of over 20 000 entries has been compiled from keywords, names and formulae in the text and tables. It covers general classes of compound, specific compounds, general types of reaction, specific and named reactions, spectral and other properties, and other topics in heterocyclic chemistry. More details are again given at the beginning of the index in Volume 8. 

The common hemlock, Conium maculatum, contain five alkaloids. Power and Tutin found a similar mixture in fool s parsley, and a volatile alkaloid resembling coniine i.s stated to occur in certain aroids. According to Svagr, water hemlock Cicuta virosa) owes its poisonous properties to toxin and not to cicutine, a name sometimes used as a synonym for coniine. The toxic properties of hemlock juice have been known ftom very early times thus it was the chief ingredient in the poison administered to criminals by the Greeks. The leaves and the unripe fruits are the parts used in medicine. The following are the names and formulae of the alkaloids —... 

The following are the names and formulas of this group of alkaloids —... 

In the following account the numbers in brackets after the name and formula of the alkaloid are the numbers of the plants in which it occurs as given in the list (p. 117). 

The large scale on which morphine is manufactured has made it possible to conduct investigations on practically unlimited supplies of factory residues, with the result that many alkaloids have been isolated from opium, of which at present twenty-five are known. In the following table, giving their names and formulae, they have been divided into five groups —... 

Papaverine, CjiHgiO N. Hesse s alkaloid of this name and formula was re-examined by Spath and Polgar and shown to be papaverine. 

The cinchona alkaloids of practical importance are quinine, quinidine, cinchonine and cinchonidine, but, in addition, over twenty others have been isolated from cinchona and cuprea species. Their names and formulae are as follows ...

In a solution prepared by adding 0.1 mol of HC1 to water, there is 0.1 mol of H+ ions, 0.1 mol of Cl- ions, and no HC1 molecules. There are six common strong acids, whose names and formulas are listed in Table 4.1. 

Give the name and formula of three hydrogen containing compounds that are not classified as acids. State for each compound one or more properties common to acids that it does not possess. 

The name of compounds whose molecules contain three or more elements, usually including oxygen, ends in the suffix ate. Thus the chemical name for limestone, whose chemical formula is CaC03, is calcium carbonate. That of green vitriol, also known as copperas, whose formula is FeS04, is iron sulfate. The names and formulas of some chemical compounds related to archaeological studies are listed in Table 7. 

Note that not all the possible oxyanions of these elements exist. If the name and formula are not given in Table 6-5, the ion is not known. If you learn the seven ions that end in -ate plus the meaning of the ending -ite and the prefixes, you will be able to write formulas for 20 oxyanions. You may double this number of names by learning an additional rule in Sec. 6.4. Note from Table 6-5 that for each central element, all ions present have the same charge. 

Ans. Ammonia and ammonium ion. Note carefully the difference between these names and formulas.
