Chapter 4: Chirality Flashcards Quizlet

WebThe aldotetroses contain two chiral carbon atoms, each of which may exist in an R- or S- form, giving rise to four stereoisomers. ... Each time we add a chiral center to a molecule, we double the possible number of stereoisomers. With 1 chiral center, there are 2 isomers, 2 chiral centers, 4 possible isomers, 3 centers, 8 isomers and 4 centers ... WebThese two stereoisomers. They're a special type of stereoisomer that we call enantiomers. We'll talk much more about number of stereoisomers in a later video. The next video, we're going to go into more detail about chiral centers and chirality centers, and how to identify the number of chiral centers in a molecule. Up next: video.
