1. shown below are IR spectra of cyclohexanecarbaldehyde (I)
and cyclohexene (II). which of the spectra A and B corresponds to
which structure (I or II)? On each 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 drying and arrow from the circled bond to the absorption
peak. include all the C-H bonds.

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...

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.
