Question
Chapter 5, Problem 5C.3AE
(i)
Interpretation Introduction
Interpretation: The overall mole fraction of phenol in the given mixture under given conditions has to be calculated.
Concept introduction: The mole fraction is used as the unit to express the concentration. It is calculated by taking the ratio of number of mole of a particular component to the total number of moles of the mixture. It is given by the formula as,
(ii)
Interpretation Introduction
Interpretation: The relative amount of two phases has to be stated using the lever rule.
Concept introduction: The lever rule is used to determine the relative amount of the components in the phases which are represented in the phase diagram. According to the lever rule, the ratio of composition of each phase of a component is equal to the ratio of distances in the phase diagram. It is represented by the formula as,

5 (a). Using the peak information you listed in the tables for
both structures, assign each peak to that portion of the
structure that produces the peak in the NMR spectrum. Draw
this diagram on your own sheet of paper and attach the sketch
of your drawing to this question.
Question 6
5 (b). Using the peak information you listed in the tables for
both structures, assign each peak to that portion of the
structure that produces the peak in the NMR spectrum. Draw
this diagram on your own sheet of paper and attach the sketch
of your drawing to this question.
Question 7
6. Are there any differences between the spectra you obtained
in Beyond Labz and the predicted spectra? If so, what were
the differences?

Interpreting NMR spectra is a skill that often requires some
amount of practice, which, in turn, necessitates access to a
collection of NMR spectra. Beyond Labz Organic Synthesis and
Organic Qualitative Analysis have spectral libraries containing
over 700 1H NMR spectra. In this assignment, you will take
advantage of this by first predicting the NMR spectra for two
closely related compounds and then checking your predictions
by looking up the actual spectra in the spectra library. After
completing this assignment, you may wish to select other
compounds for additional practice.
1. Write the IUPAC names for the following two structures:

Question 3
2. Predict the NMR spectra for each of these two
compounds by listing, in the NMR tables below, the
chemical shift, the splitting, and the number of
hydrogens associated with each predicted peak. Sort the
peaks from largest chemical shift to lowest.
