For the reaction below, focus only on 2-methyl-2-butanol
(starting material) and 2-chloro-2-methylbutane (desired product).
We will not analyze HCl or H2O by IR.
From the two IR spectra below, identify which spectrum belongs
to which molecule. Then label the IR spectrum with the molecule’s
characteristic IR peaks. Highlight or place a box around the most
characteristic peak in the starting material’s IR. You do not need
to label the fingerprint region.

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...
