WebCis/Trans isomers are never mirror images and are therefore diastereomers. 2. Stereoisomers having chiral centers - Most stereoisomers discussed in this chapter will fall into this category. Chiral centers are tetrahedral atoms (sp 3 hybridized) that are bonded to 4 different groups. In organic chemistry most chiral centers will be carbon atoms ... WebThe maximum number of stereoisomers that can exist for a compound is 2n, where n is the number of chiral centers. Chiral centers are atoms, usually C, bonded to four different groups.
