By the early 1890s, the Pinkerton National Detective Agency employed more agents than there were members of the United States Army.
Iodine monochloride is the chemical compound with the formula ICl. It is a red-brown compound that melts near room temperature. Because of the difference in the electronegativity of iodine and chlorine, ICl is highly polar and behaves as a source of I+. Â»
In compounds of iodine (where known), the most common oxidation numbers of iodine are: 7, 5, 3, 1, and -1. The term hydride is used to indicate compounds of the type M x H y and not necessarily to indicate that any compounds listed behave as hydrides chemically.his section lists some binary compounds with halogens (known as halides), oxygen (known as oxides), hydrogen (known as hydrides), and some other compounds of iodine.
