(About the definition for chirality):
[...]
> Chirality is used only for compounds that are optically active.
[...]
> The E,Z classification of molecules is restricted to Geometric isomers, and
> not to stereoisomers, so it is not involved in optical activity.
I couldn't agree more. It has been pointed out before, but unfortunately
there is no easy way to correct a definition once typed in (I'm not sure
whether there _is_ an easy way for the curators...).
No offense meant.
