WebOxidation of alkenes with the help of ozone can give alcohols, aldehydes, ketones, or carboxylic acids. Alkynes undergo ozonolysis to give acid anhydrides or diketones. If water is present in the reaction, the acid anhydride undergoes hydrolysis to yield two carboxylic acids. Ozonolysis of elastomers is also known as ozone cracking.
