Ozonolysis of Alkenes[Reaction type: Electrophilic Addition]
Summary *********Overall transformation
: C=C to 2 x C=O
***Ozonolysis implies that ozone causes the
alkene to break (-lysis) **Reagents : ozone followed by :
**a reducing work-up, either Zn in acetic acid or
dimethyl sulfide, (CH3)2S **an oxidising
work-up, usually H2O2 (under these
conditions, carboxylic acids are obtained instead of
aldehydes) ***It is convenient to view the process as
cleaving the alkene into two carbonyls ****The substituents on the
C=O depend on the substituents on the original
C=C. ***The work-up determines the oxidation state
of the products[THANK YOU VERY MUCH .HOPE THIS WILL HELP YOU ,GOOD
LUCK]
