 Custom Search Lewis Dot of Allene C3H4 Since all the atoms are in either period 1 or 2, this molecule will adhere to the octet rule. The exception, of course, being the hydrogen's. They follow the duet rule (2 electrons). From-http://en.wikipedia.org/wiki/Allene -An allene is a hydrocarbon in which one atom of carbon is connected by double bonds with two other atoms of carbon. Allene also is the common name for the parent compound of this series, propadiene. Such pair of bonds make allenes much more reactive than other alkenes. For example, their reactivity with gaseous chlorine is more like the reactivity of alkynes.
