A sample of dichloromethane has been contaminated with some 2,2-dichloropropane. The NMR spectrum of this sample shows two signals, one at 5.2 ppm and one at 1.9 ppm, corresponding to these two compounds respectively. The integrals of the two signals equate to 1:9 respectively. What is the mole percent of each compound in the mixture, or phrasing it another way, what percentage of the mixture is dichloromethane and what percentage is 2,2-dichloropropane?

A sample of tert-butyl bromide (2-bromo-2-methyl propane) has been contaminated with some methyl bromide. The NMR spectrum of this sample shows two signals, one at 1.8 ppm and one at 2.2 ppm, corresponding to these two compounds respectively. The integrals of the two signals equate to 6:1 respectively. What is the mole percent of each compound in the mixture, or phrasing it another way, what percentage of the mixture is tert-butyl bromide and what percentage is methyl bromide? Your objective is to answer this question, explaining how you reach your decision.
Below is the spectrum for 2-hexanol which has a molecular ion peak of 102. Note that 2-hexanol's molecular ion is very unstable and rapidly undergoes degradation. This is why its molecular ion peak at 102 is almost nonexistent. Give the formula and try to describe the structure that corresponds to the base peak within the spectrum.
The 13C NMR spectrum of fluoroethanoic acid shows a multiplet centred at δ = 79. When the same spectrum is recorded using proton decoupling, the multiplet collapses to a doublet with a splitting of 160 Hz. Another multiplet, but with much smaller splittings, is also seen centred at δ =179; this multiplet collapses to a doublet when decoupling is used. Explain these observations.
What will be the 1H-NMR spectrum for the next molecule BrClCHCH2COCH3 and illustrate the corresponding signals according to their chemical displacement, multiplicity and integration. Indicate two basic differences that exist between the spectra of 1H y 13C in NMR. Establish the difference between the multiplicity of a signal and the integral (integration) of the signal in spectroscopy of 1H-NMR.

Consider the aromatic compound 4-isopropyl-benzonitrile. (Benzonitrile is a benzene ring with the nitrile group on position 1.) How many signals for non-equivalent types of protons will be in its proton NMR spectrum?

Shown below are three isomers of a disubstituted benzene ring. The 1H NMR and 13C NMR spectra are also shown below for ONE of these isomers. Identify which isomer is producing these spectra? Hint: Consider the number of chemically equivalent hydrogen and carbon environments in each structure and the number of signals expected for each. In practise, overlapping of signals may occur if two or more hydrogen environments (or carbon environments for 13C NMR) are very similar to one another. This is often seen for aromatic signals in particular.
