Question

Write the formula of superoxide ion.​

Answer 1

Answer:

• Sodium superoxide (NaO2) can be prepared with high oxygen pressures, whereas the superoxides of rubidium, potassium, and cesium can be prepared directly by combustion in air. By contrast, no superoxides have been isolated in pure form in the case of lithium or the alkaline-earth metals.

Answer 2

The systematic name of the anion is dioxide(1−). The reactive oxygen ion superoxide is particularly important as the product of the one-electron reduction of dioxygen O2, which occurs widely in nature.

Explanation:

1.Superoxide is a diatomic oxygen, an inorganic radical anion, an oxygen radical and a member of reactive oxygen species. It has a role as a human metabolite, an Escherichia coli metabolite and a mouse metabolite.

2.Superoxide, which is an anion radical, is produced by the one-electron reduction of molecular oxygen.

3.If you want to distinguish oxide, superoxide and peroxide ions, generally you can use their X-ray structure well. Oxide is a single oxygen ion, superoxide and peroxide is O−O with approximate bond distance of 1.33 and 1.49 A respectively.

4.For example, these are the compounds having superoxide ion (O2). The state a oxygen in superoxides is −1/2. These are paramagnetic in nature due to presence of paired electrons, e.g. KO2,RbO2 etc.
