Chloroiodomethane

Chloroiodomethane is a chemical compound that belongs to the class of halomethanes. It is also known as iodochloromethane and is represented by the chemical formula CH2ClI.

Structure and Bonding[edit | edit source]

Chloroiodomethane is a triatomic molecule with a tetrahedral geometry. The carbon atom is at the center, bonded to a hydrogen, a chlorine, and an iodine atom. The C-I bond is longer and weaker than the C-Cl bond due to the larger size and lower electronegativity of iodine compared to chlorine.

Synthesis[edit | edit source]

Chloroiodomethane can be synthesized by the reaction of iodomethane with chlorine gas in the presence of light. The light provides the energy required to break the Cl-Cl bond in the chlorine molecule, initiating the reaction.

Uses[edit | edit source]

Chloroiodomethane is used as a reagent in organic synthesis. It is particularly useful in the Finkelstein reaction, a halogen exchange reaction used to convert alkyl chlorides or bromides to alkyl iodides.

Safety[edit | edit source]

Like other halomethanes, chloroiodomethane is a volatile and potentially hazardous compound. It can cause irritation to the eyes, skin, and respiratory tract. Proper safety measures should be taken while handling this compound.
