What is the difference between peroxide ion and super oxide ion??

Dear Student,

Superoxides: These are compounds that possess the superoxide anion with the chemical formula O₂ ^-.With one unpaired e^-, the superoxide ion is a free radical and is paramagnetic in nature. In the case of superoxides like CsO₂,NaO₂, KO₂, RbO₂ each oxygen atom is assigned an oxidation state of -1/2.

Peroxides: These are compounds containing an oxygen-oxygen single bond or the peroxide anion [O-O]^2-.The O-O group is called the peroxide group. In case of peroxides H₂O_2, Na₂O₂ each oxygen atom is assigned an oxidation state of -1.
