Question
Chapter 4, Problem 34P
Interpretation Introduction
Interpretation:
Absolute configurations of the reactant and product molecule in the given reaction of isotopically labelled ethane are to be determined.
Concept introduction:
The absolute configuration is the three dimensional spatial arrangement of substituents at a chirality center.
The Cahn-Ingold-Prelog rule system ranks the substituents in the chirality center in the order of decreasing

Thoroughly describe what is meant when a compound is considered aromatic. In your answer, provide examples and be sure to discuss how Huckel's Rule applies, and what it means to be anti-aromatic versus non-aromatic. When providing specific examples to demonstrate the requirements that you list, describe the delocalized pi electrons and sp2 hybridization. Lastly, why is benzene so special compared to alkenes like cyclohexene....both are 6-carbon atom cycles so are they chemically similar or not really similar at all?
Predict the electronic configurations of (a) the benzeneanion, (b) the benzene cation. Estimate the π-bond energy in each case.
As you might suspect, B-carotene, C,Hw precursor to vitamin A, was first isolated from carrots. Dilute solutions of B-carotene are yellow, hence its use as a food coloring. In plants, it is almost always present in combination with chlorophyll to assist in the harvesting of the energy of sunlight and to protect the plant against reactive species produced in photo- synthesis. As tree leaves die in the fall, the green of their chlorophyll molecules is replaced by the yellows and reds of carotene and carotene-related molecules. Compare the carbon skeletons of B-carotene and lycopene. What are the similarities? What are the differences? H3C. H3C CH3 CH3 CH3 H,C CH3 CH3 CH3 B-Carotene

The reaction is catalyzed by the stereospecific enzyme fumarase that utilizes only the trans form of 2-butenedioate ion (also known as fumarate) and produces only the (S)-2-hydroxysuccinate enantiomer (also known as (S)-malate). Draw the correct stereochemical structures of these two compounds of the fumarase-catalyzed reaction.
