[edit]Hello fellow Wikipedians,
I have just modified one external link on Axial chirality. Please take a moment to review my edit. If you have any questions, or need the bot to ignore the links, or the page altogether, please visit this simple FaQ for additional information. I made the following changes:
- Added archive https://web.archive.org/web/20050123014310/http://siggy.chem.ucla.edu:80/VOH/30A/Dinitrobiphenyl_(COOH)2.pdf to http://siggy.chem.ucla.edu/VOH/30A/Dinitrobiphenyl_(COOH)2.pdf#search='axial%20chirality'
When you have finished reviewing my changes, please set the checked parameter below to true or failed to let others know (documentation at {{Sourcecheck}}).

Inconsistency
[edit]According to the article, the molecule is viewed from the side with higher priority. As far as I know, priority is determined by the atomic number of each atom around the stereocenter. If I'm not mistaking chlorine has priority over oxygen and therefore the molecule 4-chloropenta-2,3-dien-2-ol should have been viewed from the other side. The change would make no difference to the classification of the molecule as R or S (Ra/Sa or P/M) which was determined correctly. Please correct me if wrong about this.Infolunch (talk) 09:59, 2 January 2021 (UTC)
- You are obviously correct about the relative atomic numbers of Cl vs O and the general idea of ranking by atomic number. But in context there is "the additional rule that the two near substituents have higher priority than the far ones." Therefore, the front are "1 and 2" vs the rear "3 and 4" regardless of how the front compare to the rear. I added a cite (with quote) from the IUPAC rules to the article.

- I have misunderstood the meaning of priority in this context. you are correct. thanks for the reference.Infolunch (talk) 18:40, 2 January 2021 (UTC)
