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).
