TODO: Verify the procedure for assigning planar chirality against IUPAC, and referenced them, which will be more authoritative than the book given. —Preceding unsigned comment added by RohanMitchell (talk • contribs) 22:09, 20 March 2010 (UTC)
What is the difference between planar chirality and axial chirality? edit
The subject/headline says it all: what is the difference between planar chirality and axial chirality?
My lecture notes discuss substituted biphenyls, including 2,2′-dimethylbiphenyl, stating that they are axially chiral.
This article cites the very same 2,2′-dimethylbiphenyl as a prime example of planar chirality.
Are planar and axial chirality synonymous?

"Are planar and axial chirality synonymous?"
No - one exhibits chirality by differenciating the enantiotopic faces of a planar molecule or ring - as in the drawn metallocene example shown on the page or in cyclophanes. The other is due to a helical arrangement about an axis - such as in chiral atropisomerism (biaryls), heptahelicene etc. The artical is confused and not correct. Note that the natural product Cavicularin exhibits both planar and axial chirality as it is a 2,2' biaryl and a cyclophane

New example images edit
Hello there. I made new images on the German wikipedia. Maybe you want to use some of them here as well? best regards. Johannes Schneider (talk) 21:00, 25 October 2021 (UTC)
