CHEMICAL GERMAN II 



das Selenblei lead selenide 



der Schwef elkohlenstoff carbon sulphide 



der Phosphorwasserstoff hydrogen phosphide 



das Tellurkupfer copper telluride 



das Fluorkalzium calcium fluoride 



das Schwef elzink zinc sulphide 



2. The name of the electronegative element follows having 

 its termination changed to -id. 



EXAMPLES : 



das Eisencarbid iron carbide 



das Kupf erchlorid copper chloride 



das Eisenphosphid iron phosphide 



das Antimonsulfid antimony sulphide 



das Kalziumfluorid calcium fluoride 



das Natriumchlorid sodium chloride 



das Magnesiumnitrid magnesium nitride 



das Bleiselenid lead selenide 



The names Schwefel, Kohlenstoff , Stickstoff, Wasserstoff and 



Sauerstoff never receive the ending -id. 



When atomic ratios other than that of I : I are to be expressed, 



prefixes are used as in English, thus : 



das Quecksilbermonochlorid das Quecksilberdichlorid 



das Antimontrichlorid das Bortrifluorid 



das Phosphortribromid das Phosphorpentabromid 



das Chromdichlorid das Chromsesquichlorid 



das Wasserstoffmonosulfid das Wasserstoffdisulfid 



In the earlier German chemical works such compounds were 



named without having recourse to Latin or Greek. Thus : 



das Zweifachschwefeleisen iron disulphide 



der Vierf achchlorkohlenstoff carbon tetrachloride 



der Fimffachchlorphosphor phosphorus pentachloride 



der Dreif achchlorstickstoff nitrogen trichloride 



The English terminations -ous and -ic are expressed in German 



by the endings -ur and -id respectively. 

 EXAMPLES : 



das Kupf erchloriir cuprous chloride 



das Kupf erchlorid cupric chloride 



das Eisenbromiir ferrous bromide 



das Eisenbromid ferric bromide 



das Eisensulfiir ferrous sulphide 



das Eisensulfid -. ferric sulphide 



das Quecksilber jodiir - mercurous iodide 



das Quecksilber jodid mercuric iodide
