A small fraction of hydrocarbon found on earth, and all currently known hydrocarbon found on other planets and moons, is thought to be abiological. [15] Hydrocarbons such as ethylene, isoprene, and monoterpenes are emitted by living vegetation. [16] Some hydrocarbons also are widespread and abundant in the Solar System.

Adding another benzene ring to form dibenzo[c,g]phenanthrene creates steric hindrance between the two extreme hydrogen atoms. [17] Adding two more rings on the same sense yields heptahelicene in which the two extreme rings overlap. [18] These non-planar forms are chiral, and their enantiomers can be isolated. [19]
