3. (3 pts.) Shown below is the IR spectrum 2-acetylcyclohexanone (the structure is provided in the spectrum). 2- acetylcyclohexanone exists as an equilibrium mixture of diketone and two enol forms. Both the diketone and enol forms can be seen in the provide IR spectrum, although the 2 different enols cannot be distinguished. The IR spectra of both enols is essentially identical and so do not be concerned with distinguishing the enols, just assign peaks to a “generic" enol. On the...
