9) What would be the difference between the 4 alcohols in IR? They all show O-H, C-H sp3, and C-H aromatic bonds. The only way to tell which one is used would be by comparing the fingerprint regions to published IR spectra of each alcohol. Alcohol 2 has an aldehyde C-H group that could be seen between 2700-2800 and 2800-2900 cm-1 Only alcohol 3 will show O-H bond around 3300 cm-1 Only alcohol 1 will show C=C aromatic bonds around 1600 cm-1 10) Assuming 5.0 mL of alcohol 2 was used and 2.2 g of the product was isolated, what is the percent yield for this reaction? The product has a molar mass of 198.00 g/mol. 11) How could the percent yield be increased for this reaction? Add NaOH to neutralize the product as it forms Add a catalyst such as H2SO4 to help speed up the reaction Add a catalyst such as HCl to help speed up the reaction Cool the reaction on ice to increase the rate of reaction 12) Is there another way that the product of this reaction…

Two bottles labelled cis-cyclohexandiol were found in a laboratory. Because of their differing melting points, the bottles clearly contained two different cis-cyclohexandiol isomers. To determine which isomer was in which bottle, the chemist decided to run ¹3C NMR spectra on a sample of each. The three possible products were as in the figure. (Figure 1) The two ¹³C NMR proton-decoupled spectra contained the following data: ● ● Figure HO spectrum of sample in bottle A: 20.20, 62.55 spectrum of sample in bottle B: 16.09, 29.52, 36.15, 63.08 OH OH OH 1 of 1 OH OH Part A Identify which isomer was present in the bottle A.
