Question

1.) Draw the keto and enol forms of dimedone.

2.) Using the Eyring equation, compute the free energy of activation for a process for which the half life [?1/2=(ln 2)/k] is 4 s.

3.) In which solvent, d7-dimethylformamide or D2O, would you think it most likely that theinterconversion rate between the keto and enol forms would be faster than the NMR timescale? Explain.

4.) Which form of dimedone would you expect to be more stable in a protic solvent? Explain.

5.) Draw the C-G and A-T base-pairs showing the hydrogen bonds as dotted lines.
