8. Sev eral students take a 1H NMR and 13C NMR spectra for an unknown compound They each propose something about the identity of the unknown. For each argument, determine whether the argument is: (10 pts) MS: No M+2 peak present, the MW is an odd number 13C NMR: 130, 125, 65, 30, 15, 10 H NMR: 5.8 (1H dd) 5.5 1.3(3H, d 1.1 (3, t) A scientific argument is valid if the data and conclusion are both true, and...
Given the Cosey, HSQC and HMBC experiments assign the
1H NMR spectrum and 13C NMR spectrum signals
of the compound. 1H peaks are labelled using lowercase
letters and 13C peaks using uppercase. Be aware that the
letters of the same peak does not necessarily refer to the position
in the molecule. For example, peak a in the 1H and peak
A in the 13C NMR are not necessarily assigned to the
same number atom. The assignment of protons 4 and...
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.

Spectroscopy Unknown. The spectra and data provided were obtained from a pure organic molecule. For 1H NMR Spectra, the integral is given in number of hydrogens (#H) or as a relative ratio. Important coupling constants (J-values) are listed next to the peaks for some examples. For some spectra, an inset (grey box) is also given showing a "zoom-in" on an important part of the spectrum Submit your answer for Quiz 3 at: https://uglabs.cbc.osu.edu/cgi-test/organic/spec-quiz.pl Mass Spectrum (not shown): [M-206 (100%) m/z...
Evaluate and investigate the
following IR Spectrum, 13C NMR Spectrum
and 1H NMR Spectrum. Identify
the most important peaks and correlate the
results as much as you can from the obtained product in
the multi-step synthesis of ethyl acetoacetate.
This is Product E from this multi-step synthesis
where Product C was identified as in the figure
below and as such, identify what product can be obtained
after the synthesis from the spectra provided. Use the template
below in analysing the...
