Which statement is incorrect?
Correct answer: D. Two pairs of enantiomers are obtained
- A. One of the products exists as three stereoisomers
- B. Two pairs of diastereomers are obtained only
- C. Only one meso stereoisomer is obtained
- D. Two pairs of enantiomers are obtained
Explanation
The correct answer is Option D: Two pairs of enantiomers are obtained because enantiomers come in pairs and a single compound cannot form two distinct pairs of enantiomers. Option A is correct as a compound can have three stereoisomers when considering both enantiomers and meso forms. Option B is correct because multiple pairs of diastereomers can exist depending on the stereochemistry involved. Option C is correct because a compound may only have one meso form, which is achiral despite having chiral centers.
