Ozonolysis concept?

Question

What is the basic concept of Ozonolysis?

Answer 1

R-CH=CH-R' >>>>>>R-CH-O-CH-R'
>>>>>>>>>>>>>>>>>>| ------- |
>>>>>>>>>>>>>>>>>>O ----- O

R and R'are alkyl groups
In fact...the reaction ends with the formation of OZONIDES and does not form aldehydes unless zinc and water is further added...
however the stability of Ozonides is very less compared to aldehydes or ketones unless the alkyl group is highly activating..since there r three oxygen groups that r highly negitively inductuve groups ( Oxygen needs two electrons to complete its octet)
Similar Reaction can also take place with alkynes and the product will lead to the formation of DIKETONES which r also less stable ...Only a futher addition of Zn, H2O and hydrogen peroxide will give two different carboxylic acids (if R and R' are differnt alkyl groups)...Acetylene is the only exception and gives GLYOXOL(also obtained by the oznolysis of BENZENE)>>>>>>CHO-CHO
This is an example for Cyclo Addition but not necessarily (1,3) i suppose..

Answer 2

Ozonolysis is a chemical reaction in which ozone oxidizes an alkene forming carbonyl compounds. This reaction is an example of 1,3-dipolar cycloaddition.
