2) Build cis-13-dimethyleyclohexane. Draw the molecule in the planar form and both chair conformations. ID the lowest energy chair conformation. Planar form Chair forms a) Are the methyl groups a) both axial, b) both equatorial, or e) one equatorial/one axial? b) Assign R or S configuration to all stereocenters (label the planar drawings). c) Is there an internal plan of symmetry? If so, label it () on each diagram that it is appropriate d) Is the molecule chiral or achiral/meso? e) What is the relationship between cis-1,.3-dimethylcyclobexane and trans-13-dimethylcyclohexane? Diastereomers Identical Conformational Isomers? Referenses a) Feist·P.-Stereochemistry of Batanes, Cyclopentanes, and Cycloheares" University of Colorado, Boulder Online, 2007. B) Carpenter, N. E. "Organic Chemistry Laboratory I" University of Minnesota, Morris 199:).
