The absorptions above 1500 in the spectrum are 1598 , 3026.3062 and 3464
3464 - this the characteristic O-H str of the alcoholic group.the broad peak shows the presence of H-bonded -OH group.
3062 and 3026 are sp2 C-H stretch
1598 is the typical aromatic ring C=C stretch.

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...

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...

18. (2 pts.) The equations for organic reactions usually focus on the desired transformation from reactant to product, other possible products such as byproducts and/or side products are often not included, even though it is understood that these are also formed in almost every organic reaction. Shown below is a complete equation for the ester synthesis reaction for the case of 2-pentanol, that includes all possible products, including the desired product, side product(s) and in this case some byproducts...
