Obtain the IR spectrum of your product. Draw your product on the spectrum and identify two IR absorptions that let you know that you have formed your product. Make sure you indicate what functional group is creating the absorption. Show everything on the spectrum. We get signals for anthracene in IR Spectra, ~ 3000cm-1 :sp2 CH stretch (aromatic) ~ 1620 cm : C=C stretch (aromatic) For maleic anhydride: Stretching band of maleic anhydride at 1856 cm-1 (low intensity) and 1780 cm-1 (medium intensity) and a band at 1707 cm -1 due to the C=O. Peak at 3000-3100 cm-1 is due to C-C

I have an NMR spectrum. There are 5 peaks. There is a doublet at 9.6 ppm (integrates to 2H) where aldehydes usually arise, don't know why there is a doublet. There is another doublet at 6.8 ppm, again integrating to 2H. There is a singlet at 4.5 ppm, integrating to 1H. There is a quartet at 3.4 ppm integrating to 2H, and lastly there is triplet at 1.2 ppm integrating to 3H. i recofnize the ethyl group but don't understand the peak at 9.6 unless it is not an aldehyde.
provide labeling on spectra 1 and 2. justify how the spectra were assigned to the compounds. GIVEN: spectrum 1: 1-bromo-4-ethylbenzene spectrum 2: (1-bromoethyl)benzene
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…

What is the energy equivalent of this stretching vibration in kcal/mole? 3. Why does 3,4-diethyl-3-hexene not have a carbon to carbon double bond stretching absorption band? 4. Why does a carbon to oxygen double bond absorption band have a greater intensity than a carbon to carbon double bond absorption band? 5. Using only IR, explain in detail how one could most easily differentiate between oct-1-ene and oct-1-yne if all carbon to carbon bonds are ignored. 6. Using only IR, explain in detail how one could most easily differentiate between butan-1-ol and butanoic acid.
Imine compounds usually show stretching bands in the IR in the range of 1690-1649cm-1 and aromatic amines show a C-N stretch at 1340-1265cm-1. A related compound, N-benzylideneaniline, does not show tautomerism and has a C-N stretch at 1678cm-1 while H2SB-1(2-(2-hydroxybenzylideneamino)phenol ) shows a C-N stretch of 1590 cm-1. Given this information, does H2SB-1 show some C-N single bond character.
