Peroxide vs. Superoxide: What's the Difference?

Edited by Huma Saeed || By Sawaira Riaz || Published on November 28, 2023
Peroxide is a compound with an oxygen-oxygen single bond, while superoxide contains an oxygen molecule with an extra electron, forming a radical.

Key Differences

Peroxides are chemical compounds containing an oxygen-oxygen single bond, often seen in bleaches and antiseptics. Superoxides, in contrast, have an oxygen molecule with an additional electron, making them more reactive and unstable.

In peroxides, the oxygen atoms share two electrons, leading to a more stable arrangement. Superoxides have unpaired electrons, resulting in high reactivity and a role in biological processes like signaling and defense.

Peroxides are commonly used in consumer products for their disinfecting properties. Superoxides, due to their reactive nature, are studied in biochemistry for their role in oxidative stress.

The formation of peroxides is typically through reactions with oxygen under controlled conditions. Superoxides are often formed spontaneously in biological systems, especially in cellular respiration.

In terms of safety, peroxides can be hazardous due to their potential for explosive decomposition. Superoxides are also dangerous but primarily due to their high reactivity and ability to damage biological molecules.
