"WebAug 17, 2024 · The E/Z nomenclature systematics instead are mostly used for configuration across double bonds i.e. naming alkenes. According to CIP rules, a compound is feasible to be named R/S or E/Z if the said molecule is chiral, or double bonded. Chiral molecules get R/S while (planar) double bonded molecules get E/Z configuration. For example, " - Chiral bonds
