Please identify the structure giving the following spectra (NMW, IR, Mass Spec, etc.) (attached) and state how you arrived at your structure (give reasons such as peak identifcation and mass, etc.).
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

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?
4. Should
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

For each ring in each structure, indicate if it is aromatic. Rationalize your decision for each ring (even those that are not aromatic). Make sure to indicate which (if any) lone pair el
A singly ionized helium atom (He+) has only one electron in orbit about the nucleus. What is the radius of the ion when it is in the n = 3 excited state?
I have an idea of how to do the problem, but that is with hydrogen. Please help and thank you very much!
