3) You have a mixture of two liquids, one with a boiling point of 40 °C and one with a boiling point of 60 °C. You correctly assembled your distillation apparatus and set your heating mantle to maximum. You obtained two fractions, but upon analysis by IR spectroscopy, you observe that each sample has characteristic IR features for both compounds. Describe what went wrong and how you might prevent that problem in the future.

Describe the differences between the infrared spectra of butanoic acid and 2-butanone

Draw structures for the three isomers 1-butyne, 1,3-butadiene, and 2-butyne. Explain how you would distinguish these compounds using IR spectroscopy. Give specific examples of peaks that would illustrate the differences.

In the esterification of  propanoyl bromide and isopropyl alcohol what product is expected? Create a detailed numbered procedure for the esterification including moles, grams and volume for all reactants and show calculations as to how much grams of product you expect to produce. Include IR peaks and the number of carbon and proton NMR peaks you expect.

2. How could you use the 4 (FOUR) forms of spectroscopy that we have discussed to give you an indication that you have 100% conversion of alcohol (cyclohexanol) to alkene (cyclohexene), i.e.-the reaction went to completion? Use ALL relevant specific signals that you could monitor to support your answer. If a technique would not help you at all, indicate the reason for this. (a) IR spectroscopy (b) Mass spectroscopy (c) BC NMR Spectroscopy (d) 'H NMR Spectroscopy

What alcohol compund is this based on this IR spectrum?

Below are three MS spectra, Spectra 1, 2, and 3. Each of this mass spectrum corresponds to either Compound A (contains one Cl in the molecular formula), Compound B (one I in the molecular formula), and Compound C (one Br in the molecular formula). Identify which spectra corresponds to which compound. Provide explanations for your choices.

4. Ethyl acetate and 2-butene-1,4-diol both have the molecular formula C4H8O2. How would you use infrared spectroscopy to distinguish between the two? Provide a thorough explanation.

Answer and provide a detailed explanation of you arrived in that answer.
