If (S)-glyceraldehyde has a specific rotation of -8.7°, what is the specific rotation of (R)- glyceraldehyde? A) -8.7° B) +8.7° C) 0.0° D) cannot be determined from the information given

Answer: B) +8.7°

Explanation: The specific rotation of enantiomers is equal in magnitude but opposite in sign. Since (S)-glyceraldehyde has a specific rotation of -8.7°, the specific rotation of its enantiomer, (R)-glyceraldehyde, will be +8.7°.
