Overview

From Wikipedia, the free encyclopedia · Read full article · Text CC BY-SA 4.0

Peroxides are a group of molecules with the structure R−O−O−R, where each R represents a radical and the O's are single oxygen atoms. Oxygen atoms are joined to each other and to adjacent elements through single covalent bonds, denoted by dashes or lines. The O−O group in a peroxide is often called the peroxide group, though some nomenclature discrepancies exist. This linkage is recognized as a common polyatomic ion, and exists in many molecules.
