WebOzonolysis In determining the structural formula of an alkene, it is often necessary to find the location of the double bond within a given carbon framework. One way of accomplishing this would be to selectively break the double bond and mark the carbon atoms that originally formed that bond. WebOzonolysis is an efficient way of oxidizing alkenes ( and alkynes as well) into their corresponding aldehydes and ketones: One of the advantages of ozonolysis compared to other oxidative cleavage reactions is that it does not over-oxidize the alkene to carboxylic acid unlike, for example, the potassium permanganate (KMnO4): tablet screen is dark
