u/SpallatedBoron

Sorry, I’m not sure if I’m being clear or coherent or anything. For example, like in the image I provided the top two molecules are an acene and a phenacene, but is there a general name for the bottom two structures?

Additionally, would they be stable, or more so than the Acene? I‘d expect the phenacene to be the most stable, then the one under it, then the one on the bottom, then the acene, but I’m not sure my intuition is right.

Sorry, thanks for taking the time to read.
