| Mar 27, 2017 at 16:53 | comment | added | jerepierre | @orthocresol I've changed it to reflect that C2 may or may not be in a chiral environment. | |

changed to reflect understanding of "chirotopic"

| Mar 27, 2017 at 16:17 | comment | added | orthocresol | As for the r/s notation, future visitors to this question may be interested in: What does lowercase r-s notation mean? and IUPAC name for 1,2,3-trichlorocyclopropane? where the notation is explained in detail with reference to the Blue Book. | |
| Mar 27, 2017 at 16:13 | comment | added | orthocresol | As far as I can tell (by reading Anslyn/Dougherty section 6.3.3) C-2 is chirotopic only in those isomers which are chiral, i.e. B and F. In the meso compounds A and C, C-2 lies within the plane of symmetry and is therefore achirotopic. So, both of you are correct. :) | |

| Oct 15, 2016 at 19:11 | comment | added | EJC | Carbon 2 is achirotopic, not chirotopic and it is called a stereocenter as it can have r/s configuration. It is not strictly a chiral center because two attached groups differ only by their configurations. | |

| Nov 3, 2014 at 19:03 | comment | added | yolo123 | Hmm. The solutions said the answer was two. Like my guess... I conclude that the solutions is mistaken. | |
