Organic Chemistry - Using the following IR anaylsis identify the
major peaks and possible functional group identity. Using the two
NMR spectra, discuss the integration of peaks, chemical shifts, and
splitting. Using the mass spectra, identify molecular weight and
important fragments to confirm the structure. Draw the fragments
that correspond to each peak in the mass spectra. Draw the
structure of the unknown that corresponds to all available data.
additional information: Unknown ‘J’ is a alkane.

Must know the unknowns name and structure.
NAME IR & 13C NMR Unknown Your mission is to determine the structure of your unknown from the molecular formula, IR and 'SC NMR spectra. Assign all of your 3C NMR absorptions. You want to know which resonances correspond to which parts of the product's structure. The best way to do this is to draw a picture of the molecule right on the NMR spectrum then label each C on the molecule with...

Provide the correct structure for your unknown based on the
spectroscopic data provided. Provide the correct name for your
compound. Either the IUPAC name, or a commonly accepted name (i.e.,
ethyl acetate in place of ethyl ethanoate) will be accepted.IR
spectrum: Assign as many peaks as possible. In particular, you
should assign peaks that were important in making your structural
interpretation (i.e. functional group peaks such as OH, C=O, N-H,
etc.).

Determine structure for each of the compounds provided on the next pages. Show work and logic, including ID calculation. Assign stretches to IR spectrum. Determine possible functional group. Use NMR spectrum to determine groupings, peaks and structure-IDENTITY of the unknown. Logic and brief explanation is required for full marks.

On the following pages are two problems. You have a molecular
formula, an IR, a 1H NMR and a 13C NMR. For
each
problem:
a. (1 pt) Calculate the index of hydrogen deficiency.
b. (4 pts) Propose a structure that is consistent with the
spectra.
c. (1 pt) Indicate the important peaks in the IR and what features
in your structure they correlate to. (Ignore the
fingerprint region.) Keep in mind that the IR can sometimes be
confusing.
