6. The mass spectrum and the infrared spectrum for an unknown hydrocarbon are shown below. From this information, suggest a structure for the hydrocarbon. Indicate on the spectra how your structure fits the data.
(See attached file for full problem description)
There are two unknown compounds, #19 and #39, and their various spectra are attached (see attachment). Using the spectra and justification, find the structures of the unknowns. The spectra include IR, UV, Mass Spec, and H and C NMR.
A) Why is GC not able to distinguish between the trans vs. cis-2-pentene products?
b) Explain why the 3-pentanol 13C-NMR spectrum contains three peaks while the trans and cis-2-pentene spectra contain five peaks (note that 13C-NMR gives a peak for each unique carbon, i.e. identical carbons show up as the same peak).
Would you please provide me with some information regarding the infra-red spectrum of caffeine. Attached I have a labeled spectra of caffeine would you please tell me how I would label it. The lines on my spectra of caffeine are :1650.49;1696.46;1548.42;1485.28;1455.52;1356.19;1237.09;758.34;744.96 all of these numbers are on my

(b) homogenization of markets
(c) implementation of Just-in-Time inventories
(d) increased strength of large competitors
(e) increased internationalization of business
You have been asked to prepare a speech to deliver to an industry group about the following topic:
1. The unabated continuation of the proliferation and fragmentation of the health professions.
2. What are the desirable aspects of this fragmentation?
3. And what is the undesirable aspects of this fragmentation?
I wonder about a mass spectrometry problem where they define which m/z that would appear for a molecule and why another m/z value does not appear that has a primary radical and a secondary cation. I know that the primary radical is unstable but the secondary cation is more stable than other products. Could one explain this by ra
