Chlorine forms number of oxides such as Cl2O , ClO2 , Cl2O6 and Cl2O7 . Chlorine andoxygen do not combine directly with each other. So, these oxides are prepared byindirect methods.
For example, Cl2O is prepared by passing Cl2 through freshly prepared yellow HgO.
HgO + Cl2 → Cl2O + Hg
Some of these oxides undergo disproportionation rather easily.
For example.
Cl2O6 + 2KOH → KClO3 + KClO4 + H2O
The oxides of chlorine are ocidic in nature. Cl2O7 is the anhydride of perchloric acid
Cl2O7 + H2O → 2HClO4
