Question

The following are the formulae for three compounds 2,3-dichorobutane written, in non-eclipsed conformations. In each instance, tell which compounds are enanatiomers and which are meso:

• A. (a) and (c) are enantiomers;(b) is meso
• B. (a) and (b) are enantiomers;(c) is meso
• C. (b) and (c) are enantiomers;(c) is meso
• D. none of these

Answer 1

The correct option is A (a) and (c) are enantiomers;(b) is meso

A and C are enantiomers because they are non superimposable mirror image of each other where as B is Meso because there mirror image are superimposable.
