What 1H NMR spectral data is expected for the compound shown? Calculate the Hydrogen deficiency and draw the correct C_4 H_9 Br isomer, (IR shows strong bands at 3000-2850 and sharp bands in the region 1300-1150cm^-1) that best fits the proton NMR spectrum shown below, Assign^1 H NMR peaks to show which protons give rise to which signal in each spectrum?
1. Propose a mechanism: Starting material: butyraldehyde Solvent: water Reagent: Potassium Hydroxide(KOH) Final product: 2-ethyl-3-hydroxy-hexanal 2. Propose a mechanism: Starting material: Methyl Propionate Solvent: water Reagent: HCl Final product: propionic acid
Propose a structure that is consistent with the spectral data below. (The spectra and data provided were obtained from a pure organic molecule. For 'H NMR spectra, the integral is given in number of hydrogens (#H) or as a relative ratio.) Mass Spectrum (not shown): [M] = 162 m/z (100%) IR Spectrum (not shown): 3022, 2980, 1685, 1600, 1510 cm (all listed are strong (s) unless otherwise indicated) 'H NMR Spectrum (300 MHz, DMSO, 25 °C) dd (J= 2 Hz)...

3. (a) From the spectral data (1H, 13C NMR, IR, MS) you were given, identify the structure of your product. Explain why you chose your particular product based on the spectroscopic data. (b) Fully assign the 1H NMR spectrum of your product (i.e. determine which peaks in the 1H NMR correspond to which hydrogens in the product) (c) Now work backwards (or consult the NMR spectra of the two reactants) and determine the structure of the two unknown reactants. Thank...
8. Give several pieces of data you gathered from the IR spectrum that aided in determining (or confirming) the structure of your unknown. For example, you might mention the presence (or absence) of certain definitive peaks (include wavenumbers). Do NOT use anything from the fingerprint region. 9. Fill in the table below with the information on each unique 1H-NMR signal. You may treat all aromatic protons as a single signal if that helps. Peak Chemical Shift (8) # of *10...
