Abstract
We examine systematically the possibility that a given reaction graph connects enantiomers. We define an enantiomeric labeling as a way to d ispose enantiomers on the graph according to specified conditions. Sin ce reaction graphs have to be symmetric, we have derived the set of en antiomeric labelings for every symmetric graph having less than 20 ver tices. For some of these graphs, this set is empty; for others it cont ains only one labeling. Unexpectedly, it appears that some graphs have many such labelings which may even have different distances between e nantiomers. As a result, the distance between enantiomers is not alway s the diameter of the graph.
