Here we have a reduction reaction. So the first step in this process, the first step in the breakdown process is an oxidation step. The last step in the synthesis process is a reduction step. Now, the second process, the second step in the breakdown process is a hydration. And the second to last step is the dehydration. Then we have an oxidation, we have a reduction, and then we have a cleavage here, and we have a condensation.
