Peroxides are a group of chemical compounds that contain an oxygen-oxygen single bond (O-O). The most common example is hydrogen peroxide, which is often used as a disinfectant and bleaching agent. Peroxides can vary in stability and reactivity, making them useful in various applications, including industrial processes and organic synthesis. In addition to hydrogen peroxide, there are other types of peroxides, such as barium peroxide and sodium peroxide, each with unique properties and uses. Peroxides can release oxygen when they decompose, which is why they are often used in reactions that require oxygen or as oxidizing agents in chemical reactions.
