I’ve noticed this as well. Working on making an image to update these cards. Will have the fix within the next day or two.
@jamesmaxwellcrew What do you think about something like this?
I think changing the (spatial isomers) to (configurational isomers) in the original image works better. iirc (don’t have a citation besides wiki rn), all stereoisomers that aren’t enantiomers are diasteromers; conformational would thus sit beneath diastereomer alongside E/Z.
I don’t think conformers should sit under diastereomers.
Kaplan 2.1 Structural isomers:
Stereoisomers differ in how these atoms are arranged in space (their wedge-and-dash pattern), and all isomers that are not structural isomers fall under this category. The largest distinction within this class is between conformational and configurational isomers. Conformational isomers or conformers differ in rotation around single (σ) bonds; configurational isomers can be interconverted only by breaking bonds.
Kaplan also has the same flowchart order as the image I suggested above.
