Textbook Question
Chapter 3.1, Problem 3.11P
If you look at your answers to the previous problems, you should find that one of the structures was expected to produce an NMR spectrum with only one signal. In that structure (problem 3.4), all six methyl groups were chemically equivalent. Using that example as guidance, propose two possible structures for a compound with molecular formula C9H18 that exhibits an NMR spectrum with only one signal.

The 1H NMR spectrum, 13C NMR spectrum, mass spectrum, and IR spectrum below belong to a chemical with the molecular formula C4H9XO, where X is a halogen. Provide a structure for that compound. You must explain how you determined the structure for full credit based on the data bellow.
The 1H-NMR spectrum of 1-bromopropane shows three signals and the 1H-NMR spectrum of 2-bromopropane shows two signals. Draw these two molecules and determine the relative integrals of each signal.
Two bottles labelled cis-cyclohexandiol were found in a
laboratory. Because of their differing melting points, the
bottles clearly contained two different cis-cyclohexandiol
isomers. To determine which isomer was in which bottle,
the chemist decided to run ¹3C NMR spectra on a
sample of each. The three possible products were as in
the figure. (Figure 1)
The two ¹³C NMR proton-decoupled spectra contained
the following data:

- From the 13C spectrum of a compound, one can assign signals to specific carbon atoms of the compound and determine the number of protons on each of those carbon atoms. Such information in conjunction with the DEPT C-13 chart will allow the appearance of the corresponding DEPT spectrum of the compound to be predicted. There are five signals (I – V) in the 13C spectrum of compound A as shown below. At the exactly same location of each of these five signals, "a peak", "no peak", or "an inverted peak" may appear in the corresponding DEPT-135 spectrum. Predict the DEPT-135 spectrum of compound A by selecting the expected signal appearance at each of these five locations in the DEPT-135 spectrum. - II II IV V in HO A 100 PPM 180 160 140 120 80 60 40 20 v At the location of signal I A. no peak v At the location of signal IIl В. а рeak v At the location of signal IIl C. an inverted peak v At the location of signal IV v A the location of signal Varrow_forwardI have an NMR spectrum.
