1. allene

   In organic chemistry, allenes are organic compounds in which one carbon atom has double bonds with each of its two adjacent carbon atoms (R2C=C=CR2, where R is H or some organyl group). Allenes are classified as cumulated dienes. The parent compound of this class is propadiene (H2C=C=CH2), which is itself also called allene. An group of the structure R2C=C=CR− is called allenyl, where R is H or some organyl group. Compounds with an allene-type structure but with more than three carbon atoms are members of a larger class of compounds called cumulenes with X=C=Y bonding.

1. Allene

   An allene is a compound in which one carbon atom has double bonds with each of its two adjacent carbon centres. Allenes are classified as polyenes with cumulated dienes. The parent compound of allene is propadiene. Compounds with an allene-type structure but with more than three carbon atoms are called cumulenes. Allenes are much more reactive than most other alkenes. For example, their reactivity with gaseous chlorine is more like the reactivity of alkynes than that of alkenes.
