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»
The iodoform test or iodoform reaction is a qualitative chemical test for the detection of ketones and aldehydes carrying an alpha methyl group. The reagents are iodine and sodium hydroxide.Only methyl ketones, or alcohols with the feature: CH3CH(OH)-R may undergo this reaction.thanal is the only aldehyde to give the iodoform reaction. Finally, OH- (aqueous) is added, which reacts with, for example, the triiodoacetone. CH3COCI3 + OH- â CHI3 + CH3COO-Iodoform, or triiodomethane (I3CH) is a pale yellow substance. It is therefore a solid at room temperature.
