full_question: The terpene ascaridole unusually possesses this functional group in a bridging position, while three bridges containing this functional group link two tertiary amines in HMTD. The smallest compound with this functional group is produced in the anthraquinone process. A Hock rearrangement of this functional group attached to cumene is used to produce phenol and acetone in the cumene process. These compounds are used to oxidize sulfides to sulfoxides or sulfones, and they are produced in autoxidation reactions. Oxidation of ketones to esters via the Baeyer-Villiger reaction and non-stereospecific epoxidation of alkenes are typically catalyzed with a compound containing a hybrid of this functional group and a carboxylic acid. mCPBA contains this functional group, which is characterized by an oxygen-oxygen single bond. For 10 points, name this functional group found in the common disinfectant H2O2.
first_sentence: The terpene ascaridole unusually possesses this functional group in a bridging position, while three bridges containing this functional group link two tertiary amines in HMTD.
raw_answer: peroxides [or hydroperoxides; or peroxyacids; or peroxycarboxylic acids; or hydrogen peroxide]
