Question
Chapter 20, Problem 20.39AP
Interpretation Introduction
Interpretation:
The way by which the configuration of the optically active hydrocarbon,
Concept introduction:
A carbon atom that has four nonequivalent atoms or groups attached to it is known as the chiral carbon atom. Chiral carbon centers are also called asymmetric or stereogenic centers. A chiral molecule is an optically active molecule. It rotates the plane of a plane polarized light.

1, part A) We observe 6 carbon stereocenters in the molecule below. Indicate each stereocenter, and give the absolute S or R configuration.
1, part B) Indicate each stereoisomer in this molecule, and give the absolute S or R configuration. Then, indicate E or Z configuration of all alkenes in it (*ignoring aromatic ring*).
The following data was collected for this experiment:
A sample of 0.8281 g of phenylsuccinic acid was dissolved in 10 mL of acetone.
This sample gave a reading, aobs, of +10.278 deg on the polarimeter.
A tube measuring 1 dm was used for the sample.
What is the major enantiomer present in this sample?
Calculate the concentration of the sample used in g/mL.
Calculate the observed specific rotation [a]obs of the sample. Give your answer to 4 significant figures.
The NMR spectrum of bromocyclohexane indicates a low field signal (1H) at δ 4.16. To room temperature, this signal is a singlet, but at -75 ° C it separates into two peaks of unequal area (but totaling one proton): δ 3.97 and δ 4.64, in ratio 4.6: 1.0. How do you explain the doubling in two peaks? According to the generalization of the previous problem, what conformation of the molecule predominates (at -75 ° C)? What percentage of the molecules does it correspond to?
