Iodine monobromide is an interhalogen compound with the chemical symbol IBr. It is a dark red solid that melts near room temperature. Like iodine monochloride, IBr is used in some types of iodometry. It serves as a source of I+. Its Lewis acid properties are compared with those of ICl and I2 in the ECW model.
Synthesis
Iodine monobromide is formed when iodine and bromine are combined in a chemical reaction:[1]
- I2 + Br2 → 2 IBr
