Exhibit 19-1
Consider the reaction below to answer the following question(s): 
-Refer to Exhibit 19-1.The exact position of the equilibrium between ketones/aldehydes and their hydrates depends on the structure of the carbonyl compound.Although the equilibrium favors the carbonyl compound in most cases,cyclopropanone forms a stable hydrate.Explain this phenomenon based on the structures of cyclopropanone and its hydrate.
