Three-carbon molecule
Three-carbon molecules are based on a skeleton made from three carbon atoms. They may be in a chain, or cycles. C3 hydrocarbons are usually gases, they are inflammable, and may be harmful to humans and the environment. The CAS registry number for three-carbon hydrocarbons is 68606-26-8. Hydrocarbons that include three atoms are: Propane C3H8 Propene C3H6 Cyclopropane C3H6 propyne C3H4 Cyclopropene C3H4 Propadiene C3H4 Cyclopropenylidene C3H2 Cyclopropyne C3H2 Tricarbon C3 References External links
