Talk:Optical isomer

What is the definition of "optical isomer" then?

 * What is the definition of "optical isomer" then? If it is a special case of enantiomer, the redirect should point to that article, not the much more general "chirality" article.  Note that a compound with chiral atoms may not have enantiomers -- or "optical isomers", whatever that is. Anyway, the term must be defined in the head of whatever article the redirect points to.

 * I guess you mean the lead/intro when you say head. Optical isomer is defined in the history section of the target. IUPAC defines it as an "Obsolescent synonym for stereoisomers with different optical properties." i.e. enantiomers and diasteromers and the use is strongly discouraged. Christian75 (talk)
