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...

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. 2. provided below are IR spectra of 1,2,3,6-tetrahydrobenzaldehyde (I)...

2. (2 pts.) Provided below are IR spectra of 1,2,3,6-tetrahydrobenzaldehyde (I) and 3-methyl-2-cyclohexen-1-one (II). Decide which of the IR 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 drawing an arrow from the circled bond to the absorption peak, as appropriate. Include all the C-H bonds. odo and II...
IR Spectroscopy of Aspirin 1. Draw the structure of aspirin and state the chemical name of aspirin. 2. Indicate the regions (circle and label on your IR spectrum) of your spectrum that correspond to a carbonyl and a hydroxyl functional group. Identify two other regions that correlate with other functional groups/structural features. Indicate these regions on your spectrum (circle and label on your IR spectrum). 3. Use your IR spectrum, melting point data, and FeCly test results to characterize the...
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. For the reaction below, focus only on 2-methyl-2-butanol...
1. In the H NMR, draw the structure of the molecule directly on the spectrum and identify each unique proton. Indicate which proton is responsible for each peak. 2. In the IR spectrum, indicate which functional group is responsible for each important peak. Attempt to identify at least five important peaks. In you discussion, indicate which peaks are most helpful in determining whether or not you converted the starting material to the desired product. 3. Compare the IR spectrum of...
