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
