Sunday 29 June 2008

Definition: A peroxide is a compound containing an oxygen-oxygen single bond. The simplest stable peroxide is hydrogen peroxide. Superoxides, dioxygenyls, ozones and ozonides compound are considered separately.

In organic chemistry, peroxide is a specific functional group or a molecule containing an oxygen-oxygen single bond (R-O-O-R’). When the other oxygen bears a hydrogen, it is called a hydroperoxide (R-O-O-H). The radical HOO· is known as hydroperoxide radical, and is thought to be involved in combustion of hydrocarbons in air.

Organic peroxides tend to decompose easily to free radicals of the form:
