A)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).
The fullly formatted problems are in the attached file.
For the compound below, determine how many peaks would be present in the compound's normal 13C decoupled spectrum.
Propose structures for compounds that fit the following data: C3H6Br2; 2H quintet at 2.4 ppm J = 6 Hz; 4H triplet at 3.5 ppm J = 6 Hz
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).
I need to identify the 2 unknowns. I was given these graphs. For each unknown, I was given IR, NMR, Mass spec and CNMR. I need the following for each graph:
IR- Peaks, range, and functional group
NMR- what each singlet and doublet represent
Mass Spec- total mass, what each line represents
CNMR - what does CNMR graph tells
Please see the attached file for the complete problems.
1. For the compound below tell how many signals you would expect the molecule to have in its normal, broadband decoupled 13CNMR spectra.
2. Identify the indicated sets of protons as unrelated, homotopic, enantiotopic, or diastereotopic.
3. For the compounds below
I have some data to help me solve a structure via High Resolution NMR, however being new to this, I am having extreme difficulty, and was wondering if someone could help please - or even point me in the right direction as how to go about solving for structure A?
A has a molecular formula: C12H15O4N.
The 13CNMRdata sh
A biochemist is studying the structure of a protein using NMR. He would like to measure the distance between hydrogens of the methyl groups of Val and Leu and other hydrogens in the molecule. Using a well established approach he is able to assign signals from the methyl groups of each Val and Leu residue in his protein. But t
On the attached pages are the combined IR, 1H NMR and 13CNMR for Problems 1 and 2. Systematically solve the structure for each one. Provide the structure in the space attached, also, fill in the information requested on the table attached.
