WebAddition reactions are typical of unsaturated organic compounds— i.e., alkenes, which contain a carbon-to-carbon double bond, and alkynes, which have a carbon-to-carbon triple bond—and aldehydes and ketones, which have a carbon-to-oxygen double bond. WebThe reaction of ozone with alkenes and alkynes causes the oxidative cleaving of the alkene or alkyne. The carbon-carbon triple bonds are replaced with carbon-oxygen double bonds, giving the required carbonyl product as shown below. Ozonolysis Mechanism The Ozonolysis mechanism proceeds via an oxidative cleavage reaction. WebThe addition of the elements of water across the triple bond of an alkyne leads to the formation of aldehydes and ketones. Water addition to terminal alkynes leads to the … trigen nagel smith \u0026 nephew
