1. A colorless, flammable gas (C₃H₄) consisting of a hydrocarbon with a triple bond between two carbon atoms; methylacetylene.
Usage: chemistry; also called methylacetylene

Examples

• Propyne is used as a chemical intermediate in organic synthesis.
• The molecular formula of propyne is C₃H₄.
• Propyne can be produced by the dehydration of propanol.
• In the laboratory, propyne is often generated and used immediately due to its volatility.
• The triple bond in propyne makes it more reactive than propane.
