10.74 The following compounds exhibit tautomerism, with a particu- ly high enol concentration. Compound 1 exhibits an enol concen- tration for (CH3)2CHCHO. Compound 2 exhibits an enol concentration of 95% (Acc. Chem. Res. 1988, 21, 442-449): of 9.1%, as compared with the enol concentration of 0.014% 2 (a) Draw the enol of compound 1 and offer an explanation for the high enol concentration, relative to (CH3)2CHCHO b) Draw the enol of compound 2, and explain why the enol is favored over the aldehyde in this case.
