Question

9. A and B are stereoisomers. They are nonsuperimposable and are mirror images of one another Which of the following best describes the relationship between A and B? A. structural isomers B. enantiomers C. confrontational isomers D. diastereomers 10. Which of the following terms best describes the pair of compounds shown: cl Br A. enantiomers, B. diastereomers, C. th D. conformational isomers e same compound 11. Which of the following terms best describes the pair of compounds shown CH C1 cl CH A. enantiomers, B. diastereomers, C. th e same compound

Explanation / Answer

9) Non-superimposable mirror images are called enantiomers. Option B is correct.

10) They are same compounds. option C is correct

Explanation: Both structures have chiral center with same absolute configuration.

11) Both are diastereomers. option B is correct.

Explanation: Two compounds having two chiral centers in which the configuration at one chiral center is same in two compounds and the cnfiguration is opposite at other chiral center in two compounds then those two compounds are called diastereomers.
