Interpretation Introduction

Interpretation: The structure of L is to be identified.

Concept introduction: Triacylglycerols are a type of lipids. They are composed of three fatty acids and glycerol. Simple triacylglycerol contains three same fatty acids while mixed triacylglycerol contains two or more different fatty acids. They are also known as triglycerides.

In the presence of ozone and ${\text{CH}}_{\text{3}}{\text{SCH}}_{\text{3}}$, oxidative cleavage occurs. In oxidative cleavage both the sigma and pi bond of the alkene is broken and two carbonyl compounds are formed. When ozone is added to the alkene, unstable intermediate molozonide is formed which rearranges to ozonide. This ozonide is reduced to form two carbonyl compounds in presence of ${\text{CH}}_{\text{3}}{\text{SCH}}_{\text{3}}$.
