- I need help with this 13C NMR, please explain how to solve it.Given the Mass Spectrum, IR spectrum, and C/H NMR spectrum, what is the spectroscopy unknown or a molecule that matches this data.hi, can someone please help me interpret this IR? it was done in the lab and I've also attached the reaction we did to obtain this IR. which peaks correspond to the product/reactant/impurities? Thanks!
- hello, thanks so much for this!! i also have an IR and Mass Spec spectra with this assignment. I figured out the IR to match these same signals and come up with this same compound, but I cant seem to figure out how to do the fragmentation on the Mass Spec. It is given then M+ = 116, but there's baRely a peak thereThe molecule ethylbenzene is seen to have the three highest fragments at m/z = 106, 91, and 65. The base peak is at 91. Explain why this occurs and draw the structure of the fragmentsA. Below is a “Name Reaction” - Clemensen reduction. Describe how the IR spectrum could be used to tell if the reactions had been successful. Provide approximate wave numbers and the corresponding functional groups for the key absorption bands and/or peaks in IR. You might want to describe from two aspects: which peak(s) of what functional group(s) should appear in the IR of the product (that is different from the reactant); which peak(s) of what functional group(s) should disappear in the IR of the product (that is present in the reactant B. For the Clemensen reduction (same reaction), describe how the 1H NMR spectrum could be used to tell if the reactions had been successful. Provide approximate chemical shifts and the integral and the “splitting” of the “unique” in the NMR spectrum. You might want to describe from two aspects: which peak(s) should have a change in chemical shift(s); which peak(s) should have a change in integral; which has a splitting change; which peak(s) will be…
- Q1. Why is it common to use CCl4 as a solvent in IR spectroscopy? Q3. After completion of the previous reaction, you end up seeing the following peaks: 3300 cm-1 (broad intense peak), 3060-3040 cm-1 (2 medium intensity peaks), 3030-3020-3010 cm-1 (3 small peaks), 1640 cm-1 (low intensity peak), 1585 cm-1 (medium intensity peak), 1410 cm-1 (medium intensity peak), 1100 cm-1 (strong intensity peak), 1010 cm-1 (medium intensity peak), 900-690 (many peaks, medium intensities). Give the molecular structure of the actual final product for the previous reaction. (Hint: it is not a carboxylic acid, nor the ketone previously drawn.) Q4. You want to take the IR spectrum of acetylene. How would you prepare your sample? Mention all important details of the sample preparation (no need to describe the acquisition).Morning, Please help Draw what you would expect to see in the 1H NMR of this compound attached. Please show the number of signalsA low-intensity peak at ?/? = 31 can be seen in the mass spectrum of methyl acetate in Figure 3. Propose a fragment that could originate from methyl acetate and be responsible for this peak.
