stereoisomerism

== English == === Etymology === From stereo- + isomerism. === Pronunciation === IPA(key): /ˌstɛɹɪəʊaɪˈsɒməɹɪzəm/ Hyphenation: ste‧re‧o‧i‧som‧er‧is‧m === Noun === stereoisomerism (countable and uncountable, plural stereoisomerisms) (chemistry) A form of isomerism in which atoms are arranged differently about a chiral centre (or centre of asymmetry). They exhibit optical activity, and in a molecule with a single chiral centre the two isomers (enantiomers) are mirror images of each other whereas in a molecule with multiple chiral centres the isomers (diastereoisomers) are not normally mirror images.
