(a)
To determine: A three dimensional representation for the given structure, each chiral centre marked by star, any planes of symmetry, any enantiomer, any diastereomers and each structure labeled as chiral or achiral.
Interpretation: A three dimensional representation for the given structure with each chiral centre marked by star, any planes of symmetry, any enantiomer, any diastereomers are to be drawn and the structure is to be labeled as chiral or achiral are to be stated.
Concept introduction: If two compounds have same molecular formula but the spatial arrangement of atoms is different, then they are known as stereoisomers. Stereoisomers are further divided into two categories: optical isomers and geometrical isomers. The two different forms in which a single chiral carbon can exist is referred to as enantiomers. The class of diastereomers includes stereoisomers that are not enantiomers. They are not the mirror images of each other. There are two or more chiral centers generally present in diastereoisomers.

- File Preview The following is a total synthesis of the pheromone of the western pine beetle. Such syntheses are interesting both because of the organic chemistry, and because of the possibility of using species specific insecticides, rather than broad band insecticides. Provide the reagents for each step. There is some chemistry from our most recent chapter in this synthesis, but other steps are review from earlier chapters.
