WebA chiral center is an atom (in this quiz, Carbon) that is bonded to FOUR different groups of atoms. While the center CAN bond to multiple of the same element, the groups they form have to be different. For example, a … WebDiastereomers are stereoisomers that are not mirror images. For example, compare these two molecules: They have the same connectivity but a different arrangement of the Br groups. The OH groups, however, are identical. So, we have two chiral centers, and only one is changed, while the other one is the same.

WebLet's apply our chirality discussion to real molecules. Consider 2-butanol, drawn in two dimensions below. Carbon #2 is a chiral center: it is sp 3-hybridized and tetrahedral (even though it is not drawn that way above), and the four substituents attached to is are different: a hydrogen (H) , a methyl (-CH 3) group, an ethyl (-CH 2 CH 3) group, and a hydroxyl … WebThe enantiomer of a molecule with multiple chiral centers is formed through configurational inversion at every chiral center. By rotating the ring of molecule III 180 degrees about the bond connected to its carbon chain, it is seen that molecules I and III are constitutionally identical with opposite configurations at every chiral center.
