Hello. I have an exam soon, and I'm trying to understand a subject, but I just dont get it! -Diasteromers, Non-superimposable, enantiomers (L,D), Epimers, Mirror images. I have looked at so many structures related to ^^. Can someone explain me very simple so I can understand the difference between them. I have tried google, I still dont get it. Thank you.
