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.

Analyze the two Newman projections and determine the relationship between the two. How would you describe the relation between conformations when they are maintained at a temperature too low to permit them to interconvert? CH3 CH3 Br. H H H H A. Identify the relationship. They are identical. They are structural isomers. They are stereoisomers. They are conformers. H H -I H Br H B. What is the relationship at low temperatures? They are identical. They are conformational diastereomers. They are structural isomers. They are conformational enantiomers.
