Getting your double bonds in a twist - How to depict unspecified stereo
I've just been adding depiction support for double bonds with unspecified stereo, and thinking about how this should be done: a squiggly bond for a substituent on the double bond, or make the double bond itself twisted? Actually, I didn't have to think too much as Rich and others (also mcule) have already worked through these same issues. In short, the IUPAC recommendation (from 2006) is best avoided, and a twisted bond should be used instead.
So, here's the result after implementing the twisted bond:
