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 the carbon tetrachloride molecule, four chlorine atoms are positioned symmetrically as corners in a tetrahedral configuration joined to a central carbon atom by single covalent bonds. Because of this symmetrical geometry, CCl 4 is non-polar.Methane gas has the same structure, making carbon tetrachloride a halomethane. As a solvent, it is well suited to dissolving other non-polar compounds, fats, and oils.It can also dissolve iodine.n 2008, a study of common cleaning products found the presence of carbon tetrachloride in very high concentrations (up to 101 mg/m 3) as a result of manufacturers' mixing of surfactants or soap with sodium hypochlorite (bleach).
