Based on the NMR spectrum in Figure 16-32, can Unknown 1 be
CH3CH2CH2CO2C6H5 or CH3CH2OCH2(CwO)C6H5? Why or why not?
With this in mind, suppose you are given the 'H NMR spectrum in Figure 16-32, which is generated from a compound (Unknown 1) having the formula C10H1202 To answer question 1, the spectrum appears to have at least four signals: one at 1.1 ppm, one at 8 = 1.8 ppm, one at 8 = 4.2 ppm, and a set of signals...

this is the 1H NMR and 13C NMR of a structure. can someone
help me find out exactly the structure ?? and also detailed as
possible? & also can you identity if the structure is an
alkane, alkyl, or an aromatic compoubd with no O or N?
please thank you

Below is the H NMR spectra for the molecule styrene.
Consider if a hydroboration reaction was preformed on styrene.
How would the H NMR of the expected product change in comparison to
styrene? Circle which peaks from the styrene spectra would
disappear and not be present in the NMR of the product.
Draw the expected product. Describe the splitting pattern of
each new proton signal that would appear in the NMR of the
product.

Identify each signal with the corresponding H atoms in the
molecule (for example, “signal 4 corresponds to the H’s in the
