Question

6. To collect an IR spectrum of your product, click on the FTIR spectrometer located to the right of the lab bench and drag the salt plate icon to the flask on the lab bench. A window containing the FTIR spectrum for your product should now open. Identify the relevant absorptions in the IR spectrum and the functional group or bond that each corresponds to. Infrared Spectroscopy Data 1. S. 2 6. 3. 7. 4 8. 7 To collect a 'H NMR spectrum of your product, click on the NMR magnet located to the right of the chalkboard and drag the NMR sample tube to the flask on the lab bench. A window containing the NMR spectrum for your product should now open. You can zoom into various portions of the NMR spectrum by clicking and dragging over the desired area. The Zoom Out button is used to zoom back out to view the full spectrum. Identify all of the peaks in the NMR spectrum and record the chemical shift, the splitting, and the number of hydrogens for each peak in the NMR table below. 1H NMR Data Peak Chemical Shift (5) Multiplicity H' Peak Chemical Shift (5) Structure: н' Multiplicity d 7 2 - 6 8 H 3 2.2 2.3 9 d 9 3-methylbutanal 4 10 5 11 6 12 Specify the multiplicity as a singlet (s), doublet (d), triplet (t) quartet (q), or multiplet (m). Specify the number of hydrogens associated with each peak. Assign the peaks from the 'H NMR table to the corresponding protons in the product. 3
