Class 11 ozonolysis

Class 11 ozonolysis- Ozonolysis is a chemical reaction that involves the cleavage of carbon-carbon double or triple bonds using ozone (O3). The reaction is commonly used in organic chemistry for the functionalization of alkenes and alkynes. The ozonolysis of alkenes results in the formation of carbonyl compounds, while the ozonolysis of alkynes produces carboxylic acid derivatives.

Here is a general overview of the ozonolysis reaction:

1. Ozonolysis of Alkenes:
   • Reaction: R1​R2​C=CR3​R4​+O3​→R1​R2​C(O)+R3​R4​C(O)
   • In this reaction, the carbon-carbon double bond is cleaved, and two carbonyl groups (C=O) are formed.
2. Ozonolysis of Alkynes:
   • Reaction: R1​R2​C≡CR3​R4​+O3​→R1​R2​C(O)OH+R3​R4​C(O)OH
   • Alkynes undergo oxidative cleavage with ozone to yield carboxylic acid derivatives.
3. Reductive Workup:
   • After ozonolysis, the resulting ozonide intermediate (O3​) is typically treated with a reducing agent (commonly zinc, dimethyl sulfide, or other reducing agents) to cleave the ozone bond and yield the final products.

It’s important to note that ozonolysis is a powerful tool in organic synthesis for structural elucidation and the preparation of specific functional groups. The reaction is often used in the laboratory to break down complex molecules into simpler fragments for further analysis.
