This lecture describes how to determine the ozonolysis product of alkenes using the shortcut method. The video was created in accordance with the latest syllabus for CBSE Class 11 Chemistry – Ozonolysis of Alkenes published by Brilliant Qatar.

Ozonolysis is a method of oxidatively cleaving alkenes using ozone ( O3 ), a reactive allotrope of oxygen. The process allows for carbon-carbon double or triple bonds to be replaced by double bonds with oxygen. This reaction is often used to identify the structure of unknown alkenes by breaking them down into smaller, more easily identifiable pieces. Ozonolysis also occurs naturally and would break down repeated units used in rubber and other polymers. On an industrial scale, azelaic acid and pelargonic acids are produced from ozonolysis.
