An enantiomer is presented below in a 3d structure and in an unfinished 2d representation. a) on the 3d structure, select – by clicking on – the chirality center. a selected atom will be outlined in blue. b) examine the 3d structure below to determine the stereochemistry of the chiral molecule. then, on the corresponding 2d structure, draw one wedge bond and one dash bond over two existing bonds to indicate the correct stereochemistry. the narrow part of each wedge-and-dash bond should be towards the chirality center.
