Hypohalite

A hypohalite is an oxyanion containing a halogen in oxidation state +1.
This includes hypoiodite, hypobromite and hypochlorite. In hypofluorite (oxyfluoride) the fluorine atom is in a −1 oxidation state.
Hypohalites are also encountered in organic chemistry, often as acyl hypohalites (see the Hunsdiecker reaction).
