why are these two enantiomers? i did their
configuration theyre both 'R'Homework Answers
Enantiomers are non-superimposable mirror images. They are characterized by having an atom attached to four different groups called asymmetric or chiral.
To determine which isomer is R or S, simple principles apply in which the Cahn-Ingold-Prelog rules intervene to prioritize the four groups attached to the chiral center.

Why the answer is D?
(I think the two epimers have opposite configuration at only
"one" stereogenic cente.)
