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»
Iodine can form inorganic and organic derivatives in various oxidation states (â1, 0, +1, +3, +5, +7) and structural features and reactivity pattern of iodine compounds in many aspects are similar to the derivatives of heavy transition metals.
