The saponification of l8O-labeled ethyl propanoate was described in Section 19.10 as one of the significant experiments that demonstrated acyl-oxygen cleavage in ester hydrolysis. The l8O-labeled ethyl propanoate used in this experiment was prepared from l8O-labeled ethyl alcohol, which in turn was obtained from acetaldehyde and l8O-enriched water. Write a series of equations showing the preparation of from these starting materials
