I have an IR spec with a peak at 1549. Which functional group could that be?
Please annotate the following NMR and IR spectra and provide a structure and name for the molecule. The formula should be C5H12O. зн зн 2Н РРМ Wavenumbers (cm-1)
annotate IR SPECTRUM fully, including finger print region! annotate HNMR and draw the correct structure CgHgNO U- S 2 8 11 10 9 CgHgNO U- S 2 8 11 10 9
Hi, I need help finding a structure for an IR spec. The Mass spec is 174m/z and the peaks I am given are 2984, 1742, 1464, and 1088cm. I have 14 hydrogens, grouped 4H: 4H: 6H, the first 4 being a singlet, the second 4 being a quartet and the 6 being a triplet. PLEASE HELP!!
For IR, annotate the major peaks used in structure determination. Indicate what is causing the particular absorption. Annotate MS spectra For NMR, label each signal ( a, b, c, ...) starting from the right. Draw the structure of the compound and label the carbons and protons using separate structures. Calculate the index of unsaturation (U). Draw individual structures for each of the NMR spectra (1HNMR and 13C) and annotate each. C,H,OBr U= 200 180 160 140 120 100 30 60...

Identify the following unkown compound in the IR spec. The unknown compound can be either ethanol, 1-propanol, 1-propanol, 1-butanol, 2-butanol, isobutanol, 2-pentanol, 3-pentanol, or iso-pentanol. %Transmittance 40 4000 3000 2984.08 2500 Wavenumbers (cm-1) 2000 1737.04 1500 1446.62 1372.35 1233.97 1097.23 1000 1043.90 937.69 846.48 786.39 633.65 607.18
Please help identify the organic compound using mass spec, ir spec, CNMR, and HNMR. From looking at the mass spec, I believe the molar mass of the uknown organic compound to be 122 g/mol From looking at CNMR, I believe there are at least 5 carbons for each of the 5 peaks. I recall from class that there can be more due to symmetry, but am not certain how to tell. Above are all of the graphs given to me...
