“Ozonolysis of alkenes involves the addition of ozone molecule to the alkene to form ozonide, and then cleavage of the ozonide by to smaller molecules.”
The reaction can be considered an organic redox reaction.
Ozonolysis of 2,3 -Dimethyl-2-butene:
The alkene that gives only acetone on ozonolysis is 2,3 -Dimethyl-2-butene.
The reaction for Ozonolysis of 2,3 -Dimethyl-2-butene is discussed below:
