Vedclass · Answer

(C) For pair $I$: The first structure is a Newman projection and the second is a wedge-dash representation. By assigning $R/S$ configurations,we find one is $R$ and the other is $S$. Thus,they are enantiomers.For pair $II$: By assigning $R/S$ configurations to the chiral centers,we find that the configurations are not mirror images of each other. Therefore,they are diastereomers.For pair $III$: Both structures represent the same meso compound. By rotating the Fischer projection or checking the symmetry,we find they are identical.Thus,the correct sequence is enantiomers,diastereomers,identical.

Indicate whether each of the following pairs are identical,enantiomers,or diastereomers?
$I$ || $II$ || $III$
