Test 2: If the molecule has only one chiral center, then the molecule is chiral. If the molecule has more than one chiral center, it is most likely chiral. The exceptions are meso-compounds, which have chiral centers but are not chiral due to the presence of a place of symmetry.Molecule 3 has a single chiral center (carbon 2). Therefore, this molecule is chiral.(Note that in this depiction, we have not specified if the NH2 group is up or down.he exceptions are meso-compounds, which have chiral centers but are not chiral due to the presence of a place of symmetry.
