How many different organic structures (from the pure theoretical viewpoint) are there with carbon and hydrogen atoms and atoms without hydrogen can be made with 5 carbon atoms only? Is there any way to count them all using Polya enumeration theory for "n" (hydro)carbonatoms? This is a follow up question from this Hydrocarbons with only 4 carbon atoms

  • $\begingroup$ ron was probably hooked to this earlier one, but for 4 C atoms it could be already considered too broad, and for 5 I wonder how it could be not. $\endgroup$ – Mithoron Oct 28 '17 at 20:05

    $\begingroup$ BTW, spiropentadiene, or bowtiediene [no, I did not make up that name], C5H4, was first synthesized in 1991 and is highly unstable. $\endgroup$ – DrMoishe Pippik Oct 29 '17 at 1:50
