Dimedone synthesis via Michael Addition reaction to determine keto/enol ratio of the synthesisized product.
Calculate the keto/enol equilibrium constant from the integrated areas of the two signals on the NMR spectrum.
Account for the splitting pattern of the 1H NMR spectrum and explain the types of protons by considering chemical shifts and integration
Use NMR data to identify keto and enol signals and decide if one of them predominates
Also, draw structures of byproducts that might form if water got into the system during the first step of the synthesis
