- Mass spectrometry of an unknown compound revealed a molecular ion at m/z 100.09. The IR spectrum, the ¹³C NMR spectrum, and the ¹H NMR spectrum are shown below. Draw the structure of this compound. 4000 220 3000 200 180 160 2000 M 1500 Wavenumbers (cm-¹) 140 120 100 1H 80 6H 1000 40 3H 20 ppm 500arrow_forwardAnalyze the 1H AND 13C NMR spectrum of C8H9NO given below and draw the structure of the compound.arrow_forwardThe 13C-NMR spectrum of 3-methyl-2-butanol shows signals at d 17.88 (CH3), 18.16 (CH3), 20.01 (CH3), 35.04 (carbon-3), and 72.75 (carbon-2). Account for the fact that each methyl group in this molecule gives a different signal.arrow_forward
- The 1H NMR spectra of two carboxylic acids with molecular formula C3H5O2Cl are shown below. Identify the carboxylic acids. (The “offset” notation means that the farthest-left signal has been moved to the rightby the indicated amount to fit on the spectrum; thus, the signal at 9.8 ppm offset by 2.4 ppm has an actual chemical shift of 9.8 + 2.4 = 12.2 ppm.)arrow_forwardUsing IR Spectroscopy to Determine the Types of Bonds in a Compound What types of bonds are responsible for the absorptions above 1500 cm−1 in compounds A and B?arrow_forwardGrignard reagents undergo a general and very useful reaction with ketones. Methylmagnesium bromide, for example, reacts with cyclohexanone to yield a product with the formula C7H14O. What is the structure of this product if it has an IR absorption at 3400 cm-1?arrow_forward
- The 1H-NMR spectrum of compound B,C7H14O , consists of the following signals: δ 0.9 (t, 6H), 1.6 (sextet, 4H), and 2.4 (t, 4H). Draw the structural formula of compound B.arrow_forwardWhat IR and H-NMR peaks would you expect to see in methyl 3-oxohexanoate (see p559, attached image)? Include band position, chemical shift, splitting in your response.arrow_forwardFollowing is the 1H-NMR spectrum of compound O, molecular formula C7H12. Compound O reacts with bromine in carbon tetrachloride to give a compound with the molecular formula C7H12Br2. The 13C-NMR spectrum of compound O shows signals at d 150.12, 106.43, 35.44, 28.36, and 26.36. Deduce the structural formula of compound O.arrow_forward
- Draw the structure for C5H10O with 1H NMR signals: δ 1.2 (s, 6H), 2.1 (bs, 1H), 5.0 (dd, 1H), 5.2 (dd, 1H), and 5.9 (dd, 1H).arrow_forwardA bottle is labeled only "Compound B (C6H₁2)" and contains a colorless liquid. You have been called in as an expert to identify this compound from its spectra: IR: 3080, 1646, 888 cm¯¹; ¹H NMR 2400 2100 8 1800 compound B (C6H₁2) 7 1500 6 M chemical shift, Hz 1200 5 4695 900 J = 6.9 Hz 600 2234 6721 3 4 chemical shift, ppm (8) The magenta numbers in the spectrum are the relative integrals in arbitrary units, and the violet numbers are coupling constants. 300 13730 2 0 1 J = 6.9 Hz 0arrow_forwardThe carbonyl absorption of an amide typically occurs in the 1630–1680 cm-1 range, while the carbonyl absorption of an ester occurs at much higher wavenumber, typically 1735–1745 cm-1. Account for this difference.arrow_forward
