When evaluating a molecule for chirality, it is important to recognize that the question of whether or not the dashed/solid wedge drawing convention is used is irrelevant. WebIt has four different groups attached to that carbon. In this case, four different atoms. So a hydrogen, a fluorine, a bromine, a chlorine. Any time you have this tetrahedral carbon that has four different groups attached to it, you create a chiral center, so this carbon right here is a chiral center, or a chirality center. rear reading lights
