What is difference between peroxide and superoxide?

Open in App

Solution

Peroxide
Superoxide
Peroxides are the compounds that are having Oxygen-Oxygen single bond.
Superoxide is the compounds that is having $O_{2}^{-}$ anion.
2. The charge present on such compound is -2. 2. They represent a charge of -1 on it.
3. As there are single bond present between the Oxygen-Oxygen so the bond length is equal to $1.44 A^{°}$ . 3. In super oxide the bond length is a little shorter than peroxide and is equal to $1.33 A^{°}$ .
4. Peroxide compounds are usuallly formed by the alkali metals and Hydrogen (non metal). 4. Superoxide is a compound formed only by metals.
5. Example: $H_{2} O_{2}, K_{2} O_{2}, {Rb}_{2} O_{2}, etc .$ 5. Example: ${RbO}_{2}, {KO}_{2}$
