Question

3. 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 diketonr and enol forms can be seen in the provide IR spectrum although the two 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 spectrum identify the peaks that are associated with a specific bond vibration bond by drawing the functional group for that bond, circling the specific vibrating bond and drawing an arrow from the Circle to Bond to the absorption peak, as appropriate. include all c-h bonds.

need help thank you!
