CLH Pre-laboratory Questions and Problems 1. Dimedone can exist in either the keto (1) or enol (2) tautomeric form. OH с HCl - H3C. C HẠC | 0 PHỤCo 2 Predict the 'H NMR and IR spectra of 1 and 2. Answer must include functional groups and wave numbers in cm for IR spectrum.

During this laboratory session we will use the Claisen rearrangement to transform phenyl allyl ether (1) into 2- allyl phenol (2). The phenol results from the tautomerization of the initial product of the Claisen rearrangement to restore aromaticity as shown below. You have yet to learn that keto-enol tautomerization usually favors the ketone, but in this case the restoration of aromaticity provides a driving force for the formation of the enol).

Label the NMR structure and IR peaks on the carbonyl
condensation and answer the questions please
Part 1:
Draw the structure of the product and show all bonds to the
hydrogens. Label the different sets of hydrogens (i.e. Ha. Hb, H1,
H2, etc.) based on which ones are equivalent and which ones are
not.
Create a table that summarizes the chemical shift, integration,
multiplicity, the proton assignment, and justification of each
signal.
