"chiral center" vs. "chirality center"Edit
"chiral center" vs. "chirality center"? Is there any difference (it seems the two are used interchangeably). Suggest changing to one or emphasizing the difference (quick google poll would indicate chiral center is more common than chirality center). — Preceding unsigned comment added by Zzzzort (talk • contribs) 22:38, 31 January 2011 (UTC)
The flash animation was horrible.
Wrong definition chirality centerEdit
I have reverted definition for chirality center which is fact is a definition for chiral carbon:
A chirality center is a stereocenter, consisting of an atom with four different entities, giving rise to two enantiomers.
Definition needs clarification for stereogenic unit!Edit
- I am not sure about the correct definition of stereocenter here. IUPAC does not seam to mention stereocenter. The IUPAC definition of stereogenic unit encompasses tetrahedral chirality (and inorganic voodoo etc), cis-trans alkene etc isomerism and, from my reading, axial chirality. In the WP article on axial chirality it states: Axial chirality is a special case of chirality in which a molecule does not possess a stereogenic center (the most common form of chirality in organic compounds) but an axis of chirality.
Stereogencity and chirotopicityEdit
As Mislow and Siegel (1984, cited) say, stereogenic and chiral have nothing to do with each other, and the two things should be separated (you cannot define one in term of the other!). The definition of stereogenic center (axis, plane) is correct as stated. Definition of chiral is Lord Kelvin's (mirror image not superimposable) and it's a property of the object as a whole. Chiral center or chirality center are oxymorons. IUPAC has not come to terms with this in the past 30 years. — Preceding unsigned comment added by 188.8.131.52 (talk) 06:08, 23 October 2014 (UTC)
