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?

[Review Topics] [References) The cyclohexane derivative shown exists primarily in the more stable of the two available chair conformations. Give the position, axial or equatorial, of each of the three groups shown in the more stable chair conformation. If a group divides its time equally between axial and equatorial positions, indicate this with ax/eq. The table of "Axial Strain Energies for Monosubstituted Cyclohexanes" found in the "Strain Energy Increments" section of the Reference tool is useful for answering this question. 6CH2CH3 Group a is Group b is Group c is Submit Answer Retry Entire Group 9 more group attempts remaining 1:06 PM 5П/2021 f12 insert prt sc delete & backspace 6 8 9.
