iodine trichloride is a chemical compound that forms in a reaction between chlorine and iodine. It is a highly reactive compound that can corrode or burn metals, so it should be handled with care.

iodine trichloride

iodine trichloride (ICl3) is a bright yellow interhalogen chemical compound that forms in a reaction between iodine and chlorine. It is often used in organic synthesis as a catalyst, and it can also be used as an antiseptic and a laboratory reagent.

It is produced in the laboratory by heating a mixture of iodine and chlorine gas at 105 degC. It is then dissolved in water, and neutralized with sodium hydroxide or sodium thiosulfate.

In addition to its reactivity, iodine trichloride is very toxic and corrosive. It can damage skin, eyes, and mucous membranes if inhaled. Therefore, it should be stored in glass ampoules and worn proper protection.

The valence bond theory is used to determine the hybridization of iodine in ICl3. Iodine has one 5s orbital and three 5p orbitals, which fuse together to form five sp3d orbitals with trigonal bipyramidal geometry. The lone pairs of electrons occupy the equatorial positions to minimize the bond pair – lone pair repulsions and achieve stability.

iodine trichloride can be used as an analytical and research agent, but it is not commonly available for industrial use. It is generally sold through chemical suppliers. It is very corrosive, so it should be stored in glass ampoules.
