Question: 21
6. The following reaction results in:
- A. retention of relative configuration and a change in the absolute configuration.
- B. a change in the relative and absolute configurations.
- C. retention of the relative and absolute configurations.
- D. retention of the absolute configuration and a change in the relative configuration.
Correct Answer: C
Explanation:
The relative configuration is retained because the bonds of the stereocenter are not broken; thus the positions of groups around the chiral carbon are maintained. The absolute configuration is also retained because both the reactant and product are (R).
