- What is the structure of the unknown? Determine it by analyzing the spectroscopic data given in IR, MS, 1H NMR, 13C NMR (Broadband decoupled with carbon types) and fully substantiate your answer with key supporting data from each spectrum.The 1H NMR spectrum for the commonly employed reactant epichlorohydrin is shown below. Despite featuring only a few signals, this spectrum provides an interesting case of assignment through the use of multiplicities and coupling constants. Can you assign the signals and explain the observed differences in geminal coupling constants?Label the significant peaks in the IR and NMR spectra. When analyzing the signals in the 1H NMR, be sure to include all appropriate information. For example: 3H, singlet, 0 neighbors, and c (the letter referring to the corresponding unique type of hydrogens that were labeled in the structure). It is recommended to provide more analysis for each signal than what is described above, when necessary, such as labeling any coupling constants if any are provided. For 13C NMR label each peak to the corresponding carbon in your suggested structure. Include calculating degrees of unsaturation.
- Propose a structure that is consistent with the following 1H NMR spectra. In each case, the molecular formula is provided. For spectra with numbers at the bottom of the signal you will need to determine the integration, others with numbers above the signal integration has been determined for you.Sketch the spectra that would be obtained for 2-chloroethanol: The four parts of a DEPT 13C NMR spectrum.Shown on the next two pages are the mass, IR and NMR spectra for anunknown organic molecule. Based on the spectra provided, determine thestructure of the molecule. You do not need to assign spectral peaks.Remember to ignore the 13 C NMR triad at 77 ppm that comes from the NMRsolvent.
- Show how the NMR spectrum of 2-bromo-2-methylbutane would look like, include approximate chemical shifts, integration ratios, and signal multiplicity. Briefly state your reasoning so i can understand better, thanks!Organic chemistry 2: from the attached NMR spectrum what can be the proposed molecule that corresponds to the spectrum. Please discuss how how you arrived at the identity of the compound.can someone provide me with the peaks and data from the IR spectrums in a table 1) table 2) table and also explain both of them to me?
- Please help with the following Organic Chemistry question regarding NMR for the compoundTwo isomers have NMR chemical shifts of 5.5 and 7.0. What would be the coalescence time in a 500 MHz NMR?Please help, am using old tests to study for MCAT and i need help with this question! Which compounds (from the picture attached) corresponds to the 4H NMR in the image attached. Annotate the spectra with any and all relevant signals that demonstrate the relationship and support your answer choice.Explain the meaning behind your annotations and how they correspond to the structure you choose. thanks in advance
