Rules for chirality

WebbCHFClBr is therefore a chiral molecule that exists in the form of a pair of stereoisomers that are mirror images of each other. As a rule, any tetrahedral atom that carries four different substituents is a stereocenter, or a stereogenic atom. However, the only criterion for chirality is the nonsuperimposable nature of the object.
