1B. Can 1H NMR spectroscopy be used to differentiate between the two compounds? Briefly explain why or why not. Predict the 1H NMR spectrum for each compound (include integration, multiplicity, and approximate chemical shift). Put it in data table format.
Why do aldehydes, esters, and amides all have a strong absorption in the 1630-1780 cm1 region of their IR spectra? A) The bond between H and the sp³-hybridized C in these functional groups vibrates in this energy range. B) Each of these functional groups has at least two resonance structures, and the different vibrations of the resonance structures give off energy in this region. C) The bond between O and the sp²-hybridized C in these functional groups vibrates at a frequency in this energy range. D) Light at this wavenumber causes the average C to O bond length to increase which causes more of this light to be transmitted. E) An electron in the bond of these functional groups gets excited to the * orbital.
Assume you are carrying out the dehydration of 1-methylcyclohexanol to yield 1-methylcyclohexene. How could you use infrared spectroscopy to determine when the reaction is complete?
Answer and explain in detail how you arrived at that answer.
6) Complete the spectroscopy data tables for a compound with molecular formula C6H12O. Determine the structure of the compound. Any labile protons, if they exist, will not be present in this particular 1H NMR spectrum.
7. How could you distinguish between 1-butanol and diethyl ether by infrared spectroscopy? 1-butanol OH both C4H10O 8. How could you distinguish between methyl butanoate and pentanoic acid by infrared spectroscopy? ha pentancic acid diethyl ether OH both CsH100 OCH3 methyl butanoate

Here are proton NMR data for 1-bromopropane: Ha : triplet (2H) 3.32ppm; Hb : multiplet (2H)1.81ppm; Hc : triplet (3H) 0.93ppm. (Relative integrations shown in parentheses.) a. Through how many bonds can a hydrogen split another hydrogen? b. According to this splitting rule, does Ha split Hc ? c. Is your answer in part a) consistent with the multiplicity listed for peak clusters a and c? d. How many hydrogenssplit Hb ? e. Upon very close inspection of the proton NMR spectrum of 1-bromopropane, you wouldfind that peak cluster b has at least six peaks. Is this consistent with your answer in part d)? f. Speculate as to why any peak cluster with more than four peaks is listed simply as a"multiplet."
Following are infrared spectra of nonane and 1-hexanol. Assign each compound its correct spectrum.
