Question

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 not? (4 pts) OH OH OH OH OH Identical a. nedora. Enantiomery or fresco identical? a. Enantiomers or identical? a. Enantiomers or identical? b. Meso yes or no? b. Meso: yes or no? b. Meso: yes or no? b. Meso: yes or no? 5.
