# Ozonolysis mechanism question

Is this mechanism will be similar to ozonolysis ?

My try :

My Question is will B be the answer ? And what does Me2S do ?

• Me2S reduces the ozonide and any remaining ozone. I think the reaction will take place on the more electron rich double bond. The product you have drawn is not one of the options offered among the answers. Nov 28 '18 at 13:20
• @Waylander should the Answer be B ? Nov 28 '18 at 13:27
• I highly doubt that the reagent in the first step is O2, and if that's the case, then it's oxidation reaction. But, I'm not sure! Nov 28 '18 at 13:45
• @rv7 its O3 ,Ozonolysis will happen I think Nov 28 '18 at 13:47

The first part of your question has been answered in the comment, as for the part about what does $$\ce{Me2S}$$ do:
The mechanism used here is reductive ozonolysis and $$\ce{Me2S}$$ acts a reducing reducing agent itself getting oxidised to dimethysulphoxide $$\ce{(Me)2SO}$$ (DMSO).
As for the mechanism of reductive ozonolysis with $$\ce{Me2S}$$ here's a helpful link.
