Experiment 10: Modeling Chirality and Cycloalkanes 4. Several compounds are shown below. For each, make two models: one model of the compound as shown, and the other where each tetrahedral stereocenter is inverted. Compare the two models side-by-side to see if the model with the inverted stereocenter(s) is the enantiomer, or if it is identical to the original. Remember, you can rotate around o-bonds to place the molecule in the conformation with the highest symmetry. Is each compound meso or...
