Halogen oxides
Halogen oxides are halogen - oxygen - compounds of the form XO 2 , X 2 O 7 , X 2 O 5 or X 2 O. X is halogen other than fluorine (there is no fluorine oxides, but only oxygen fluoride ), O for oxygen. They can act as bleaching agents , disinfectants (example: chlorine oxide ) and oxidizing agents (example: perchlorate ).
| Connection type | chlorine | bromine | Iodine |
|---|---|---|---|
| XO 2 | Chlorine dioxide | Bromine dioxide | Iodine dioxide |
| X 2 O 5 | Dichloro pentoxide | Dibromopentoxide | Diiodopentoxide |
| X 2 O 7 | Dichloroheptoxide | Dibromoheptoxide | Diiodheptoxide |
| X 2 O | Dichloro oxide | Dibromoxide | Diiodine oxide |
Example chlorine
As a halogen-oxygen compound, chlorine can have the following oxidation states:
| connection | Oxidation level of chlorine |
|---|---|
| Cl 2 O, HClO | +1 |
| HClO 2 | +3 |
| ClO 2 | +4 |
| HClO 3 | +5 |
| Cl 2 O 7 , HClO 4 | +7 |
