WebDiol cleavage is another example of a redox reaction; periodic acid, HIO 4, is reduced to iodic acid, HIO 3. Ozonolysis is a method of oxidatively cleaving alkenes or alkynes using ozone ( O3 O 3 ), a reactive allotrope of oxygen. The process allows for carbon-carbon double or triple bonds to be replaced by double bonds with oxygen.

Under controlled conditions, KMnO 4 oxidizes primary alcohols to carboxylic acids very efficiently.

WebOxidation with CrO3: Chromium trioxide acts as an oxidizing agent. It is the acidic anhydride of chromic acid. It is purple-colored solid; and in hydrous conditions, it is a bright orange-colored compound. It also has carcinogenic (cancer-causing) properties. WebSo, there are two things happening here; 1) the OH group is oxidized to a carbonyl, and 2) the C-C bond with the oxygens is cleaved. And the pattern is a primary OH group gives formaldehyde, secondary OH groups …
