網頁2024年9月10日 · 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 ... 網頁View Stereochemistry Alternate Lecture_R6(1) (2).ppt from CHEMISTRY 11 at Rutgers University.

網頁However, a stereogenic center can also be a trivalent atom whose bonds are not in the same plane, such as phosphorus in P-chiral phosphines (PRR′R″) and sulfur in S-chiral sulfoxides (OSRR′), because a lone-pair of electrons is present instead of a fourth bond. bought cheap ptz camera but cant accessa it網頁Question.
