WebSep 10, 2024 · 3. When my textbook is discussing stereoisomers with more than one chiral centers, it's using notation like (2 S ,3 S) being an enantiomer with (2 R ,3 R) and so forth. I understand R and S configuration, and I'm guessing there are two items in each brackets to represent the two chiral centers (so 2 S, 3 S would at least mean that both chiral ...
