Acenaphthene is a polycyclic aromatic hydrocarbon consisting of naphthalene with an ethylene bridge connecting positions 1 and 8. An alternative name, 1,2 dihydroacenaphthylene, emphasizes that it is a hydrogenated form of acenaphthylene. It is a constituent of coal tar.
It does not appear to be carcinogenic.
