Interpretation Introduction

Interpretation: The E or Z configuration to the double bonds in neoprene is to be assigned. The stereoisomer of neoprene in which the double bonds have the opposite configuration is to be drawn.

Concept introduction: The E or Z configuration of the double bonds is determined by prioritizing the groups attached to the carbon atoms of the double bond. The groups are prioritized on the basis of atomic number of their atoms. The group that contain atom with higher atomic number is given higher priority. When the groups with same priority are on the same side of the double bond the configuration is Z and when the groups are on the opposite side of the double bond then the configuration is E.

Stereoisomers share the same connectivity and differ only in the way their atoms are arranged in space. Draw the structure of a compound that is a stereoisomer of cis-1,2- dibromocyclobutane. (Note that the question asks for a different stereoisomer of the named compound and not the named compound itself.) • Use the wedge/hash bond tools to indicate stereochemistry where it exists. • In cases where there is more than one answer, just draw one.
It is easy to imagine a cyclohexane as a flat hexagon and a lot of the time we draw it that way. Looking at 1,3,5-triethylcyclohexane we cannot tell the stability of the molecule from looking at the flat 2D drawing. Explain why we need to look at the 3D configuration and what conformation (axial,equatorial) would each of the three ethyl groups be in for the most stable configuration.
