WebGood question – and the answer is yes tertiary amines are chiral, however due to "inversions" only certain types can be isolated as the pure enantiomer. For the ones that aren't fixed you almost instantaneously get a racemic mixture, which masks the chirality. WebFor example, for a molecule with 1 chiral carbon, the number of stereoisomers is 2 1 = 2 and for a molecule with 2 chiral carbons, the number of stereoisomers is 2 2 = 4. The Fischer projection is a simple two-dimensional drawing of a molecule’s stereoisomers. If the OH group on the chiral carbon furthest from the carbonyl is pointing left ...
