- You are given two IR spectra - one belongs to Cyclopentanol ( alcohol) and the other belongs to cyclopentanone (Ketone) but not told which is which. Explain how you can distinguish which IR spectra belongs to the alcohol and which one belongs to the ketone .Morphine, heroin, and oxycodone are three addicting analgesic narcotics. How could IR spectroscopy be used to distinguish these three compounds from each other?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.
- How do the IR spectra of the isomers cyclopentane and pent-1-ene differ?Can you use IR spectroscopy to differentiate between ketones and aldehydes?Based on the spectra you located, does your molecule have a carbonyl? If so, what functional group is it a part of (carboxylic acid, ketone, aldehyde, ester, amide) and what is the frequency (in wavenumbers) of the absorption peak? If not, what is the approximate frequency range for a carbonyl? Does your molecule have either an –O-H or –N-H bond? If so, what functional group is it a part of (carboxylic acid, alcohol, amine, amide) and what is the frequency (in wavenumbers) of the absorption peak? If not, what are the approximate frequency ranges for an –O-H and an –N-H bond? Does your molecule have either an alkyne or nitrile functional group? If so, which functional group is it and what is the frequency (in wavenumbers) of the absorption peak? If not, what is the approximate frequency range for a triple bond?
- Morphine, heroin, and oxycodone are three addicting analgesicnarcotics. How could IR spectroscopy be used to distinguish these threecompounds from each other?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…Is this HNMR spectrum for 3-methoxybenzoic acid, 4 methoxybenzoic acid or 4 methylbenzoic acid? Please explain why and explain peaks, shifts, etc.
