please explain answer so i can understand how to slove for further problems! thank you !!...
Please explain how you proposed the structure. Thank you!
The 'FI-NMR spectrum shown is that of a compound with formula C,H,O,. This compound has an IR absorption at 1716 cm. Propose a structure.
can
someone help me with these problems, and explain how they got the
answers? thanks in advance!
QUESTION 1 An unknown compound produced a mass spectrum with a molecular ion peak of m/z 58 Propose a molecular formula containing just carbon and hydrogen. Calculate its HDI (degrees of unsaturation). HDI QUESTION 2 An unknown compound produced a mass spectrum with a molecular ion peak of m/z 58. Propose a molecular formula containing carbon, hydrogen and one oxygen atom. Calculate its...
Compound A: C6H14O
I've gathered that the Unsaturation Number is 0, so there is no
double bond or ring present. (I've also attached the IR and NMR
spectra on the bottom.)
But I'm having a hard time answering the following
questions.
Based on the molecular formula and the UN/DBE you calculated, check all the functional groups that could be present in compound A? Earlier, using the molecular formula and the UN/DBE, you came up with a list of functional groups...
Hints for identifying compounds in multiple-choice problems (problems 1:5); 1. Closely compare the given compounds. Determine which piece of information (molecular weight from MS, number of peaks in the NMR, presence of a special functional group in the IR, etc) would be the easiest for distinguishing between the given compounds. You might not need to use all types of given spectra to find your correct compound! 2. Based on your answer from step 1, consult the appropriate spectrum first. For...
Thank you!Please
Help
Review the following spectral data and provide: the molecular ion's m/z(mass/charge) structurally account for the MS peaks at 105 m/z, 77 m/z, and 51 m/z. the major functional group(s) from IR spectrum (d) a probable name and structure for the compound.
NMR Help please!
Based on the molecular formula and the UN/DBE you calculated, check all the functional group that could be present in compound B? Examine the IR spectrum provided for Compound B. The peaks below 1500 cannot be used to make any structural assignments because they are i fingerprint region. There are the two important peaks in this IR spectrum, What is each peak most likely due to? Earlier, using the molecular formula and the UN/BE, you came up...
Unknown 315-S20-2
Can someone help me fill out the table on the right side
please

Please include detailed explanations so that I can clearly
understand how to solve these problems. Thank you!
3) Draw the structure, showing the stereochemistry, of the chiral products A, B and C. tBuOK CH2SO2CI 2 B он NaCN rate = k [B][NaCN] 4) Draw the structure of the two products resulting from the following reaction. What is the realtionship between these two products? Br LDA rate = k [D][LDA] Br D Relationship:
Please name the unknown compound based on the images below.
Write notes that reasonably justify the structure. Be as detailed
as possible and please write very clearly. WILL RATE for detailed
answer!! Hint: has 2 carbon atoms but no more than 7.
1. Identify all major functional groups in the IR spectra
2. Identify all peaks and H and C-NMR spectra
3. Identify the molecular mass of the unknown from the mass
spectrum
4. Determine the pattern of fragmentation from...
if you could also explain how you can determine the answer, I
would really appreciate it!
1. (15 points) Assign the resonances in the spectrum shown. The resonances on the spectrum are labelled A-D. On the lines provided, write the label that corresponds to each of the groups. The multiplicity (s = singlet, d = doublet, etc) and the integrals are given for each resonance. OCH3 + S, 6H H3 C CH₂ H OCH₃ x D s, 3H d, 2H...
