    1. (1S,2R)-1-fluoro-2-methylcyclohexane SOLUTION
    2. cis-1,3-dimethylcyclobutane SOLUTION
    3. (1R,3R)-1-ethyl-3-iodocyclopentane SOLUTION
  2. Name the following ring structures. SOLUTION
If you made some mistakes or want to practice more, review the concepts that gave you trouble and work on this extra problem. If you're good, move to the problem below ;)

Problem 9.2: Substituted Cyclohexane Conformations
  1. Draw the two possible chair conformations and select the most stable for the following molecules. SOLUTION
  1. Label each of the following pairs of structures as enantiomers, diastereomers, structural isomers, or representations of the same compound (identical). SOLUTION
If you made some mistakes or want to practice more, review the concepts that gave you trouble and work on this extra problem. If you're good, move to the next lecture ;)
